crypto: atmel-tdes - remove unnecessary static in atmel_tdes_remove()
Remove unnecessary static on local variable tdes_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 17079 8704 128 25911 6537 drivers/crypto/atmel-tdes.o after: text data bss dec hex filename 17039 8616 64 25719 6477 drivers/crypto/atmel-tdes.o Signed-off-by: Gustavo A.
