Subject: [patch 3/5] S3C2410: Add error print if we cannot add attribute
Date: Tue, 20 May 2008 13:49:57 +0100	[thread overview]
Message-ID: <20080520125030.375895346@fluff.org.uk> (raw)
In-Reply-To: 20080520124954.001898813@fluff.org.uk

[-- Attachment #1: simtec/simtec-drivers-fb-s3c2410-warningfix.patch --]
[-- Type: text/plain, Size: 1329 bytes --]

Fix the following warning by checking the result of
device_create_file and printing an error but not removing
the device (loss of debug registers is not fatal).

drivers/video/s3c2410fb.c:905: warning: ignoring return value of 'device_create_file', declared with attribute warn_unused_result
