Subject: [PATCH] thermal/drivers/ti-soc-thermal/bandgap Remove unused variable 'val'
Git-commit: d473327f8f53418691cb2944a45da3e9ea51f9bf
Patch-mainline: v5.13-rc1
References: git-fixes

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.
