2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang75-141/+4
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-06-03i2c: Check for address validity on client registrationJean Delvare1-7/+26
Do basic address validity checks when a client is being registered. We already had checks in place for devices which are being detected, but not for devices which are simply instantiated. This is a very basic check. We don't want to do strict checking here because some devices are known to infringe the I2C address constraints (e.g. IR receivers at 7-bit address 0x7a while this value is supposedly reserved for 10-bit addresses.) So we assume the caller knows what it is doing. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Matthieu Castet <castet.matthieu@free.fr>

2010-06-01FS-Cache: Remove unneeded null checksDan Carpenter1-20/+16
fscache_write_op() makes unnecessary checks of the page variable to see if it is NULL. It can't be NULL at those points as the kernel would already have crashed a little higher up where we examined page->index. Furthermore, unless radix_tree_gang_lookup_tag() can return 1 but no page, a NULL pointer crash should not be encountered there as we can only get there if r_t_g_l_t() returned 1.

2010-05-31net: sock_queue_err_skb() dont mess with sk_forward_allocEric Dumazet4-24/+33
Correct sk_forward_alloc handling for error_queue would need to use a backlog of frames that softirq handler could not deliver because socket is owned by user thread. Or extend backlog processing to be able to process normal and error packets. Another possibility is to not use mem charge for error queue, this is what I implemented in this patch.

In xt_register_table, xt_jumpstack_alloc is called first, later xt_replace_table is used. But in xt_replace_table, xt_jumpstack_alloc will be used again. Then the memory allocated by previous xt_jumpstack_alloc will be leaked.

2010-05-30CPU: Avoid using unititialized error variable in disable_nonboot_cpus()Rafael J. Wysocki1-1/+1
If there's only one CPU online when disable_nonboot_cpus() is called, the error variable will not be initialized and that may lead to erroneous behavior. Fix this issue by initializing error in disable_nonboot_cpus() as appropriate. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
