From ffa56e540c3949c4560dcce45eca247819e183c1 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Thu, 4 Nov 2010 22:59:56 +0100 Subject: [PATCH] mac80211: Remove redundant checks for NULL before calls to crypto_free_cipher() crypto_free_cipher() is a wrapper around crypto_free_tfm() which is a wrapper around crypto_destroy_tfm() and the latter can handle being passed a NULL pointer, so checking for NULL in the ieee80211_aes_key_free()/ieee80211_aes_cmac_key_free() wrappers around crypto_free_cipher() is pointless and just increase object code size needlesly and makes us execute extra test/branch instructions that we don't need. Btw; don't we have to many wrappers around wrappers ad nauseam here? Anyway, this patch removes the redundant conditionals. Signed-off-by: Jesper Juhl Signed-off-by: John W.
