Subject: drm/xe/tlb: Init range tilemask err to zero
X-Git-Tag: v7.2-rc1~141^2~27^2~83
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2b923203b0f0ad1f1f56b956fd0b23dc4fcc73dd;p=thirdparty%2Fkernel%2Flinux.git

drm/xe/tlb: Init range tilemask err to zero

Initialize err = 0 in xe_tlb_inval_range_tilemask_submit to prevent a
possible uninitialized value return in the case where the tile_mask
somehow doesn't match any available tile ids.

This targets a static analysis issue.
