H A D | selftest_workarounds.c | cc649a9e Wed May 27 09:05:09 CDT 2020 Arnd Bergmann <arnd@arndb.de> drm/i915: work around false-positive maybe-uninitialized warning
gcc-9 gets confused by the code flow in check_dirty_whitelist:
drivers/gpu/drm/i915/gt/selftest_workarounds.c: In function 'check_dirty_whitelist': drivers/gpu/drm/i915/gt/selftest_workarounds.c:492:17: error: 'rsvd' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I could not figure out a good way to do this in a way that gcc understands better, so initialize the variable to zero, as last resort.
