This avoids the problematic case: if (condition) i2c_hid_dbg(ihid, "Blah blah %d\n", i); else do_something_very_important(); Which looks correct, however with the previous macro definition, this expands to the unexpected: if (condition) { if (debug) \ dev_printk(KERN_DEBUG, &ihid->client->dev, "Blah blah %d\n", i); else do_something_very_important(); } Signed-off-by: Benjamin Tissoires <benjamin.tissoires@gmail.com> Reviewed-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Microsoft published the protocol specification of HID over i2c: http://msdn.microsoft.com/en-us/library/windows/hardware/hh852380.aspx This patch introduces an implementation of this protocol. This implementation does not includes the ACPI part of the specification. This will come when ACPI 5.0 devices enumeration will be available. Once the ACPI part is done, OEM will not have to declare HID over I2C devices in their platform specific driver.

2012-11-15s390/3215: fix tty close handlingHeiko Carstens1-7/+5
The 3215 console always has the RAW3215_FIXED flag set, which causes raw3215_shutdown() not to wait for outstanding I/O requests if an attached tty gets closed. The flag however can be simply removed, so we can guarantee that all requests belonging to the tty have been processed when the tty is closed. However the tasklet that belongs to the 3215 device may be scheduled even if there is no tty attached anymore, since we have a race between console and tty processing. Thefore unconditional tty_wakekup() in raw3215_wakeup() can cause the following NULL pointer dereference: 3.465368 Unable to handle kernel pointer dereference at virtual kernel address (null) 3.465448 Oops: 0004 #1 SMP 3.465454 Modules linked in: 3.465459 CPU: 1 Not tainted 3.6.0 #1 3.465462 Process swapper/1 (pid: 0, task: 000000003ffa4428, ksp: 000000003ffb7ce0) 3.465466 Krnl PSW : 0404100180000000 0000000000162f86 (__wake_up+0x46/0xb8) 3.465480 R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:0 CC:1 PM:0 EA:3 Krnl GPRS: fffffffffffffffe 0000000000000000 0000000000000160 0000000000000001 3.465492 0000000000000001 0000000000000004 0000000000000004 000000000096b490 3.465499 0000000000000001 0000000000000100 0000000000000001 0000000000000001 3.465506 070000003fc87d60 0000000000000160 000000003fc87d68 000000003fc87d00 3.465526 Krnl Code: 0000000000162f76: e3c0f0a80004 lg %r12,168(%r15) 0000000000162f7c: 58000370 l %r0,880 #0000000000162f80: c007ffffffff00 xilf %r0,4294967295 >0000000000162f86: ba102000 cs %r1,%r0,0(%r2) 0000000000162f8a: 1211 ltr %r1,%r1 0000000000162f8c: a774002f brc 7,162fea 0000000000162f90: b904002d lgr %r2,%r13 0000000000162f94: b904003a lgr %r3,%r10 3.465597 Call Trace: 3.465599 (<0400000000000000> 0x400000000000000) 3.465602 <000000000048c77e> raw3215_wakeup+0x2e/0x40 3.465607 <0000000000134d66> tasklet_action+0x96/0x168 3.465612 <000000000013423c> __do_softirq+0xd8/0x21c 3.465615 <0000000000134678> irq_exit+0xa8/0xac 3.465617 <000000000046c232> do_IRQ+0x182/0x248 3.465621 <00000000005c8296> io_return+0x0/0x8 3.465625 <00000000005c7cac> vtime_stop_cpu+0x4c/0xb8 3.465629 (<0000000000194e06> tick_nohz_idle_enter+0x4e/0x74) 3.465633 <0000000000104760> cpu_idle+0x170/0x184 3.465636 <00000000005b5182> smp_start_secondary+0xd6/0xe0 3.465641 <00000000005c86be> restart_int_handler+0x56/0x6c 3.465643 <0000000000000000> 0x0 3.465645 Last Breaking-Event-Address: 3.465647 <0000000000403136> tty_wakeup+0x46/0x98 3.465652 3.465654 Kernel panic - not syncing: Fatal exception in interrupt 01: HCPGIR450W CP entered; disabled wait PSW 00020001 80000000 00000000 0010F63C The easiest solution is simply to check if tty is NULL in the tasklet.

2012-11-14TTY: hvc_console, fix port reference count going to zero prematurelyPaul Mackerras1-7/+0
Commit bdb498c20040 "TTY: hvc_console, add tty install" took the port refcounting out of hvc_open()/hvc_close(), but failed to remove the kref_put() and tty_kref_put() calls in hvc_hangup() that were there to remove the extra references that hvc_open() had taken. The result was that doing a vhangup() when the current terminal was a hvc_console, then closing the current terminal, would end up calling destroy_hvc_struct() and making the port disappear entirely. This meant that Fedora 17 systems would boot up but then not display the login prompt on the console, and attempts to open /dev/hvc0 would give a "No such device" error. This fixes it by removing the extra kref_put() and tty_kref_put() calls.

2012-11-09sparc: Add sparc support for platform_get_irq()Andreas Larsson1-0/+7
This adds sparc support for platform_get_irq that in the normal case use platform_get_resource() to get an irq. This standard approach fails for sparc as there are no resources of type IORESOURCE_IRQ for irqs for sparc. Cross platform drivers can then use this standard platform function and work on sparc instead of having to have a special case for sparc.

2012-11-09gianfar: ethernet vanishes after restoring from hibernationWang Dongsheng1-1/+4
If a gianfar ethernet device is down prior to hibernating a system, it will no longer be present upon system restore. For example: ~# ifconfig eth0 down ~# echo disk > /sys/power/state <trigger a restore from hibernation> ~# ifconfig eth0 up SIOCSIFFLAGS: No such device This happens because the restore function bails out early upon finding devices that were not up at hibernation. In doing so, it never gets to the netif_device_attach call at the end of the restore function. Adding the netif_device_attach as done here also makes the gfar_restore code consistent with what is done in the gfar_resume code.
