[PATCH] scsi: st: remove redundant variable pointer stp
Posted by Colin Ian King 3 years, 8 months ago
Variable stp is assigned a value that is never read, the assignment
and the variable stp are redundant and can be removed.

Cleans up clang scan build warning:
drivers/scsi/st.c:4253:7: warning: Although the value stored to 'stp'
is used in the enclosing expression, the value is never actually
read from 'stp' [deadcode.DeadStores]
