Subject: drm/qxl: remove set but not used variable 'bo_old'
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fb8cd60c8418aebe91f773cfa32409119b96cdde;p=openwrt%2Fstaging%2Fblogic.git

drm/qxl: remove set but not used variable 'bo_old'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/qxl/qxl_display.c: In function 'qxl_primary_atomic_update':
drivers/gpu/drm/qxl/qxl_display.c:538:17: warning:
 variable 'bo_old' set but not used [-Wunused-but-set-variable]

It's not used any more after 4979904c62b9 ("drm/qxl: use shadow bo directly")
