crypto: img-hash - remove unnecessary static in img_hash_remove()
Remove unnecessary static on local variable hdev. 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
14842 6464 128 21434 53ba drivers/crypto/img-hash.o
after:
text data bss dec hex filename
14789 6376 64 21229 52ed drivers/crypto/img-hash.o
