Hello there,
I just tried out cppcheck-1.47 on the linux-2.6.38-rc4 source code.
It said
[arch/powerpc/kernel/cacheinfo.c:380]: (error) Possible null pointer
dereference: cache - otherwise it is redundant to check if cache is null at
line 382
The source code is
WARN_ONCE(cache && cache->level != level,
"cache level mismatch on lookup (got %d, expected %d)\n",
cache->level, level);
if (!cache)
I agree with cppcheck. Suggest code rework.
Regards
David Binderman
