Subject: [patch 02/11] fat: cleanup fat_put_super()
Date: Fri, 14 Aug 2009 12:42:44 -0000	[thread overview]
Message-ID: <20090814123548.213452171@linutronix.de> (raw)
In-Reply-To: 20090814122657.114987508@linutronix.de

[-- Attachment #1: fat-cleanup-nls-unload.patch --]
[-- Type: text/plain, Size: 1160 bytes --]

unload_nls() can be called with a NULL pointer now. Remove the pointer
checks and the NULLification of the pointers as the data structure
which contains the pointers is kfree'd right away.
