Subject: crypto: atmel - use list_first_entry_or_null to simplify find_dev
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c708d3fad4217f23421b8496e231b0c5cee617a0;p=thirdparty%2Flinux.git

crypto: atmel - use list_first_entry_or_null to simplify find_dev

Use list_first_entry_or_null() to simplify atmel_sha_find_dev() and
remove the now-unused local variable 'struct atmel_sha_dev *tmp'.
