2015-10-26coccinelle: Improve checking for missing NULL terminatorsDaniel Granat
Extend checking on tables containing structures which are initialized without specifying member name. Added new tables for checking: i2c_device_id and platform_device_id.

2015-10-26coccinelle: misc: remove "complex return code" warningsJohan Hovold
This effectively reverts 932058a5d5f9 ("coccinelle: misc: semantic patch to delete overly complex return code processing"). There can be both symmetry and readability reasons for not wanting to do the final function call as part of the return statement and to maintain a clear separation of success and error paths. Since this is in no way mandated by the coding standard, let's just remove this semantic patch to avoid having "clean up" patches being posted over and over in response to these Coccinelle warnings.

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail.

This makes an effort to find cases where the argument to sizeof is wrong in memory allocation functions by checking the type of the allocated memory when it is a double pointer and ensuring the sizeof argument takes a pointer to the the memory being allocated.
