Subject: checkpatch: add check for array allocator family argument order
Date: Fri, 4 Nov 2022 15:05:23 +0800
These array allocator family are sometimes misused with the first and
second arguments switched.
Same issue with calloc, kvcalloc, kvmalloc_array etc.
Bleat if sizeof is the first argument.
