From: Michel Dänzer <michel.daen...@amd.com>
Fixes server reset.
Pointed out by clang:
../../src/radeon_kms.c:2721:9: warning: variable 'pitch' is used uninitialized
whenever 'if' condition is false [-Wsometimes-uninitialized]
if (!info->front_buffer) {
^~~~~~~~~~~~~~~~~~~
../../src/radeon_kms.c:2765:27: note: uninitialized use occurs here
pScrn->displayWidth = pitch / cpp;
^~~~~
../../src/radeon_kms.c:2721:5: note: remove the 'if' if its condition is always
true
if (!info->front_buffer) {
^~~~~~~~~~~~~~~~~~~~~~~~~
../../src/radeon_kms.c:2680:14: note: initialize the variable 'pitch' to
silence this warning
int pitch;
^
= 0
