From: Lin Ruizhe Date: Wed, 21 Apr 2021 08:42:56 +0000 (+0800) Subject: thermal/drivers/ti-soc-thermal/bandgap Remove unused variable 'val' X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d473327f8f53418691cb2944a45da3e9ea51f9bf;p=linux.git thermal/drivers/ti-soc-thermal/bandgap Remove unused variable 'val' The function ti_bandgap_restore_ctxt() restores the context at resume time. It checks if the sensor has a counter, reads the register but does nothing with the value. The block was probably omitted by the commit b87ea759a4cc. Remove the unused variable as well as the block using it as we can consider it as dead code.
