crypto: geode-aes - Fix some code style issues
This fixes some code style issues like: - Use #include <linux/io.h> instead of <asm/io.h> and #include <linux/delay.h> instead of <asm/delay.h> - Use "foo *bar" instead of "foo * bar" - Add a space after the for or while sentence and before the open parenthesis '(' - Don't use assignments in a if condition Signed-off-by: Chihau Chau <chihau@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
