Do not discard the const qualifier of the function argument, and drop
|
|||
|
|
the redundant local variable `keyp`.
|
|||
|
|
|
|||
|
|
avc_sidtab.c: In function ‘sidtab_hash’:
|
|||
|
|
avc_sidtab.c:23:9: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual]
|
|||
|
|
23 | keyp = (char *)key;
