Xext: Fix buggy checks.
XvMCScreenKey is defined as XvMCScreenKeyRec's address, so will never be NULL. Use the check proposed by Alan Coopersmith and Jeremy Huddleston instead. Those warnings go away accordingly: | CC xvmc.lo | xvmc.c: In function 'ProcXvMCListSubpictureTypes': | xvmc.c:490:22: warning: the comparison will always evaluate as 'false' for the address of 'XvMCScreenKeyRec' will never be NULL [-Waddress] | xvmc.c: In function 'XvMCExtensionInit': | xvmc.c:671:21: warning: the comparison will always evaluate as 'false' for the address of 'XvMCScreenKeyRec' will never be NULL [-Waddress] | xvmc.c: In function 'XvMCFindXvImage': | xvmc.c:749:22: warning: the comparison will always evaluate as 'false' for the address of 'XvMCScreenKeyRec' will never be NULL [-Waddress] Reviewed-by: Alan Coopersmith <alan.coopersmith@oracle.com> Signed-off-by: Cyril Brulebois <kibi@debian.org>
