Subject: [PATCH] platform: x86: dell-smo8800: remove redundant assignments to byte_data

From: Colin Ian King <colin.king@...onical.com>

Variable byte_data is being initialized and re-assigned with values that
are never read. Remove these as these redundant assignments. Cleans up
clang warning:

drivers/platform/x86/dell-smo8800.c:106:2: warning: Value stored to 'byte_data'
is never read
