Subject: [PATCH AUTOSEL 5.4 137/459] drm/amd/display: remove set but not used variable 'bp' in bios_parser2.c

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

[ Upstream commit 589d8d282ebe1eab2dd8b1fba3e60322787a50e6 ]

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

drivers/gpu/drm/amd/display/dc/bios/bios_parser2.c: In function bios_get_board_layout_info:
drivers/gpu/drm/amd/display/dc/bios/bios_parser2.c:1826:22: warning: variable bp set but not used [-Wunused-but-set-variable]

It is introduced by commit 1eeedbcc20d6 ("drm/amd/display:
get board layout for edid emulation"), but never used,
so remove it.
