Subject: [PATCH] [RESEND] usb: gadget: Remove the LUN checks which are always true
Date: Sun, 8 May 2011 15:56:17 +0300 [thread overview]
Message-ID: <20110508125616.GA7153@maxin> (raw)
Comparing an unsigned integer with greater than or equal to zero is
always true. So, it is safe to remove similar checks from
'f_mass_storage.c' and 'file_storage.c'
