Subject: Fix sparse false positives re BUG_ON(ptr)
From: Alexey Dobriyan <adobriyan@xxxxx>
sparse now warns if one compares pointers with integers. However, there are
false positives, like:
fs/filesystems.c:72:2: warning: Using plain integer as NULL pointer
Every time BUG_ON(ptr) is used, ptr is checked against integer zero. Avoid
that and save ~70 false positives from allyesconfig run.
mentioned by Al.
