drm/i915: fix build for CONFIG_BUG=n
If CONFIG_BUG=n __WARN_printf won't be defined leading to the below
build failure. The double underscores should have told us to steer clear
of it anyway.
drivers/gpu/drm/i915/intel_display.c: In function ‘assert_pll’:
drivers/gpu/drm/i915/intel_display.c:1027:2: error: implicit declaration
of function ‘__WARN_printf’ [-Werror=implicit-function-declaration]
I915_STATE_WARN(cur_state != state,
Use WARN(1, ...) instead. It handles CONFIG_BUG=n gracefully and, with
the constant condition, a sane compiler should reduce it to
__WARN_printf.
This is a regression introduced by
