Subject: [PATCH AUTOSEL 4.9 046/141] drm/radeon: remove set but not used variable 'blocks'

From: zhengbin <zhengbin13@...wei.com>

[ Upstream commit 77441f77949807fda4a0aec0bdf3e86ae863fd56 ]

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

drivers/gpu/drm/radeon/radeon_combios.c: In function radeon_combios_get_power_modes:
drivers/gpu/drm/radeon/radeon_combios.c:2638:10: warning: variable blocks set but not used [-Wunused-but-set-variable]

It is introduced by commit 56278a8edace ("drm/radeon/kms:
pull power mode info from bios tables (v3)"), but never used,
so remove it.
