Remove unnecessary static on local variable sha_dd. Such variable is initialized before being used, on every execution path throughout the function. The static has no benefit and, removing it reduces the object file size. This issue was detected using Coccinelle and the following semantic patch: https://github.com/GustavoARSilva/coccinelle/blob/master/static/static_unused.cocci In the following log you can see a significant difference in the object file size. This log is the output of the size command, before and after the code change: before: text data bss dec hex filename 30005 10264 128 40397 9dcd drivers/crypto/atmel-sha.o after: text data bss dec hex filename 29934 10208 64 40206 9d0e drivers/crypto/atmel-sha.o Signed-off-by: Gustavo A.
