IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there is no need to do that again from its callers. Drop it.

@ from include/linux/err.h #define IS_ERR_VALUE(x) unlikely((x) >= (unsigned long)-MAX_ERRNO) ... static inline bool __must_check IS_ERR_OR_NULL(__force const void *ptr) { return !ptr || IS_ERR_VALUE((unsigned long)ptr); }

"!ptr" appears not covered with IS_ERR_OR_NULL. (only the IS_ERR part seems covered)

Right, the first patch of the series has fixed that.
