From: Jesper Juhl Date: Mon, 7 Nov 2005 09:01:32 +0000 (-0800) Subject: [PATCH] kfree cleanup: misc remaining drivers X-Git-Tag: v2.6.15-rc1~489 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6044ec8882c726e325017bd948aa0cd94ad33abc;p=linux-2.6 [PATCH] kfree cleanup: misc remaining drivers This is the remaining misc drivers/ part of the big kfree cleanup patch. Remove pointless checks for NULL prior to calling kfree() in misc files in drivers/.
