When possible, sleeping is (usually) better than delaying; however, don't bother callers of udelay < 10us, as those cases are generally not worth the switch to usleep [akpm@linux-foundation.org: fix mismatched parentheses] Signed-off-by:

Make error message say 'ERROR: do not initialise globals to 0 or NULL' rather than 'ERROR: do not initialise externals to 0 or NULL'. Makes more sense in the context since there is an extern keyword in C and that is a global declaration within the scope of the current file. Signed-off-by:

I've got a false positive when spaces are present at the beginning of a line. So I add this check, obviously excluding to check the lines in the middle of comments. For instance this code passes the checkpatch test: +struct davinci_mcbsp_data { + unsigned int fmt; + int clk_div; +}; + +static struct davinci_mcbsp_data mcbsp_data; Where, before the string "int clk_div", I have 4 spaces (\040 ascii character). With v2.6.34 scripts/checkpatch.pl script I get: scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch total: 0 errors, 0 warnings, 201 lines checked 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch has no obvious style problems and is ready for submission. That is not correct. Instead with the proposed patch I get: scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch WARNING: please, no space for starting a line, excluding comments #63: FILE: sound/soc/davinci/davinci-i2s.c:165: + int clk_div;$ WARNING: please, no space for starting a line, excluding comments #95: FILE: sound/soc/davinci/davinci-i2s.c:406: + return 0;$ total: 0 errors, 2 warnings, 201 lines checked That is correct.

Change the check suggesting replacement of asm-includes with linux-includes. Exceptions to this rule are easier to extend now. Add memory.h because ARM has a custom one. Signed-off-by:

Getting and putting arrays of pointers with flex arrays is a PITA. You have to remember to pass &ptr to the _put and you have to do weird and wacky casting to get the ptr back from the _get. Add two functions flex_array_get_ptr() and flex_array_put_ptr() to handle all of the magic. [akpm@linux-foundation.org: simplification suggested by Joe] Signed-off-by:

kmsg_dump takes care to sample the global variables inside a spinlock, but then goes on to use the same variables outside the spinlock region too. Use the correct variable. This will make the race window smaller. Found by gcc 4.6's new warnings. Signed-off-by:

misc_deregister() returns an error only when it attempts to unregister the device that is not registered. This is the driver's bug. Most of the drivers don't check the return value of misc_deregister(). (It is not bad thing because most of kernel *_unregister() API always succeed and do not return value) So it is better to indicate the error by WARN_ON() in misc_deregister(). Signed-off-by:

Using: gcc (GCC) 4.5.0 20100610 (prerelease) The following warning appears: init/main.c: In function `do_one_initcall': init/main.c:730:10: warning: `calltime.tv64' may be used uninitialized in this function This warning is actually correct, as the global initcall_debug could arguably be changed by the initcall. Correct this warning by extracting a new function, do_one_initcall_debug, that performs the initcall for the debug case. Signed-off-by:

Cleanup, no functional changes. - __set_personality() always changes ->exec_domain/personality, the special case when ->exec_domain remains the same buys nothing but complicates the code. Unify both cases to simplify the code. - The -EINVAL check in sys_personality() was never right. If we assume that set_personality() can fail we should check the value it returns instead of verifying that task->personality was actually changed. Remove it. Before the previous patch it was possible to hit this case due to overflow problems, but this -EINVAL just indicated the kernel bug. OTOH, probably it makes sense to change lookup_exec_domain() to return ERR_PTR() instead of default_exec_domain if the search in exec_domains list fails, and report this error to the user-space. But this means another user-space change, and we have in-kernel users which need fixes. For example, PER_OSF4 falls into PER_MASK for unkown reason and nobody cares to register this domain.
