From: Jesper Juhl Date: Mon, 7 Nov 2005 09:01:27 +0000 (-0800) Subject: [PATCH] kfree cleanup: drivers/mtd X-Git-Tag: v2.6.15-rc1~494 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fa671646f61182cd18234461a6e65f50c6558695;p=linux-2.6 [PATCH] kfree cleanup: drivers/mtd This is the drivers/mtd part of the big kfree cleanup patch. Remove pointless checks for NULL prior to calling kfree() in drivers/mtd/.
