MAINTAINERS: Remove Mark M. Hoffman

File lm75.h used to include <linux/hwmon.h> for SENSORS_LIMIT() but
this function is gone by now. Instead we call clamp_val() so we should
include <linux/kernel.h>, where this function is declared.

Pull MTD fixes from David Woodhouse:
"This fixes a couple of problems. Firstly, some people are actually
still using old small-page flash and we broke it by removing the ready
check.
Secondly. fix the handling of partitions on Broadcom 47xx devices.
Recent changes had made it misdetect the location of the NVRAM and
scribble over the bootloader when it tried to update the variables
there. With predictably sad results."

Pull ARM SoC bug fixes from Arnd Bergmann:
"Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of
pinctrl definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
- Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge
conflict here, we still want to remove it.
- missing bits for clocks on imx and s5pv210
- missing header inclusions in mmp and shmobile
- typos in s5pv210 camera and vt8500 clock support code
and three trivial fixes for pre-3.8 bugs:
- an old bogus build warning in the joystick driver
- a misleading Kconfig description
- a NULL pointer check on davinci"

4740f73fe5 "mfd: remove use of __devexit" removed the __devexit annotation
on the twl4030_madc_remove function, but left an __exit_p() present on the
pointer to this function. Using __exit_p was as wrong with the devexit in
place as it is now, but now we get a gcc warning about an unused function.
In order for the twl4030_madc_remove to work correctly in built-in code, we
have to remove the __exit_p.

ARM normally has an accurate clock source, so
we can theoretically use analog joysticks more
accurately and at the same time avoid the
build warning
#warning Precise timer not defined for this architecture.
from the joystick driver.
Now, why anybody would use that driver no ARM I have no
idea, but Ben Dooks enabled it in the s3c2410_defconfig
along with a bunch of other drivers, even though that
platform has neither ISA nor PCI support. It still
seems to be the right thing to fix this quirk.

This partially reverts commit 1696e6bc2ae83734e64e206ac99766ea19e9a14e
("mtd: nand: kill NAND_NO_READRDY").
In that patch I overlooked a few things.
The original documentation for NAND_NO_READRDY included "True for all
large page devices, as they do not support autoincrement." I was
conflating "not support autoincrement" with the NAND_NO_AUTOINCR option,
which was in fact doing nothing. So, when I dropped NAND_NO_AUTOINCR, I
concluded that I then could harmlessly drop NAND_NO_READRDY. But of
course the fact the NAND_NO_AUTOINCR was doing nothing didn't mean
NAND_NO_READRDY was doing nothing...
So, NAND_NO_READRDY is re-introduced as NAND_NEED_READRDY and applied
only to those few remaining small-page NAND which needed it in the first
place.

idr_get_new*() and friends are about to be deprecated. Convert to the
new idr_alloc() interface.
There are some peculiarities and possible bugs in the converted
functions. This patch preserves those.
* drv_insert_node_res_element() returns -ENOMEM on alloc failure,
-EFAULT if id space is exhausted. -EFAULT is at best misleading.
* drv_proc_insert_strm_res_element() is even weirder. It returns
-EFAULT if kzalloc() fails, -ENOMEM if idr preloading fails and
-EPERM if id space is exhausted. What's going on here?
* drv_proc_insert_strm_res_element() doesn't free *pstrm_res after
failure.
Only compile tested.

The commit 2e124b4a390ca85325fae75764bef92f0547fa25 removed the checks
that prevented qt2_process_read_urb() from trying to put chars into
ttys that weren't actually opened. This resulted in 'tty is NULL'
warnings from flush_to_ldisc() when the device was used.
The devices use just one read urb for all ports. As a result
qt2_process_read_urb() may be called with the current port set to a
port number that has not been opened. Add a check if the port is open
before calling tty_flip_buffer_push().

Good job. I was too lazy to bisect for bad commit;)
Reading the code I found problematic kthread_should_stop call from netlink
connector which causes the oops. After applying a patch, I've been testing
owfs+w1 setup for nearly two days and it seems to work very reliable (no
hangs, no memleaks etc).
More detailed description and possible fix is given below:
Function w1_search can be called from either kthread or netlink callback.
While the former works fine, the latter causes oops due to kthread_should_stop
invocation.
This patch adds a check if w1_search is serving netlink command, skipping
kthread_should_stop invocation if so.

The Kconfig symbol SERIAL_S3C2412 got removed in commit
da121506eb03ee5daea55404709110b798bd61d9 ("serial: samsung: merge
probe() function from all SoC specific extensions"). But it also added a
last reference to that symbol. The commit and the tree make clear that
CPU_S3C2412 should have been used instead.

With commit 835d844d1 (8250_pnp: do pnp probe before legacy probe), the
8250 driver was renamed to 8250_core. This means any existing usage of
the 8259.<xxxx> module parameters or as a kernel command line switch is
now broken, as the 8250_core driver doesn't parse options belonging to
something called "8250".
To solve this, we redefine the module options in a dummy function using
a redefined MODULE_PARAM_PREFX when built into the kernel. In the case
where we're building as a module, we provide an alias to the old 8250
name. The dummy function prevents compiler errors due to global variable
redefinitions that happen as part of the module_param_ macro expansions.

This could have been either ARCH_S5P64X0 or CPU_S5P6450. Looking at
commit 2555e663b367b8d555e76023f4de3f6338c28d6c ("ARM: S5P64X0: Add UART
serial support for S5P6450") - which added this typo - makes clear this
should be CPU_S5P6450.

The InsydeH2O BIOS (version dated 09/12/2011) has the following in
its pnp resouces for its serial ports:
$ cat /sys/bus/pnp/devices/00:0b/resources
state = active
io disabled
irq disabled
We do not check if the resources are disabled, and create a bogus
ttyS* device. Since commit 835d844d1a28e (8250_pnp: do pnp probe
before legacy probe) we get a bogus ttyS0, which prevents the legacy
probe from detecting it.
Note, the BIOS can also be upgraded, fixing this problem, but for people
who can't do that, this fix is needed.

I've managed to find an 8 port version of the card 4 port card which was discussed here:
http://marc.info/?l=linux-serial&m=120760744205314&w=2
Looking back at that thread there were two issues in the original patch.
1) The I/O ports for the UARTs are within BAR2 not BAR0. This can been seen in the original post.
2) A serial quirk isn't needed as these cards have no memory in BAR0 which makes pci_plx9050_init just return.
This patch fixes the 4 port support to use BAR2, removes the bogus quirk and adds support for the 8 port card.

Remove the extra code left over when the serial driver was changed

mpc512x platform clock code names PSC clocks as "pscX_mclk" but
the driver tries to get "pscX_clk" clock and this results in
errors like:
mpc52xx-psc-uart 80011700.psc: Failed to get PSC clock entry!
The problem appears when opening ttyPSC devices other than the
system's serial console. Since getting and enabling the PSC clock
fails, uart port startup doesn't succeed and tty flag TTY_IO_ERROR
remains set causing further errors in tty ioctls, i.e.
'strace stty -F /dev/ttyPSC1' shows:
open("/dev/ttyPSC1", O_RDONLY|O_NONBLOCK|O_LARGEFILE) = 3
dup2(3, 0) = 0
close(3) = 0
fcntl64(0, F_GETFL) = 0x10800 (flags O_RDONLY|O_NONBLOCK|O_LARGEFILE)
fcntl64(0, F_SETFL, O_RDONLY|O_LARGEFILE) = 0
ioctl(0, TCGETS, 0xbff89038) = -1 EIO (Input/output error)
Only request PSC clock names that the platform actually provides.
