Subject: [PATCH AUTOSEL 5.4 125/459] drm/amd/powerplay: remove set but not used variable 'data'

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

[ Upstream commit 4bf321c177c74f7d834956387cd74805c3098322 ]

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

drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c: In function vega10_get_performance_level:
drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c:5217:23: warning: variable data set but not used [-Wunused-but-set-variable]

'data' is introduced by commit f688b614b643 ("drm/amd/pp:
Implement get_performance_level for legacy dgpu"), but never used,
so remove it.
