[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Variable retval is being assigned a value that is never read, the
variable is redundant and can be removed.

Cleans up clang scan build warning:
drivers/pci/controller/pci-versatile.c:37:10: warning: Although the value
stored to 'retval' is used in the enclosing expression, the value is never
actually read from 'retval' [deadcode.DeadStores]
