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
