Subject: [PATCH] libselinux: sidtab_hash(): do not discard const qualifier
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

||
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;

||
| ^
