From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nicholas Mc Guire Subject: [PATCH] i2c: img-scb: match return type of wait_for_completion_timeout Date: Sun, 8 Feb 2015 08:12:35 -0500 Message-ID: <1423401155-8955-1-git-send-email-hofrat@osadl.org> Return-path: Sender: linux-i2c-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Wolfram Sang Cc: James Hogan , Ezequiel Garcia , Andrew Bresticker , linux-i2c-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Nicholas Mc Guire List-Id: linux-i2c@vger.kernel.org Return type of wait_for_completion_timeout is unsigned long not int. ret in img_i2c_reset_bus() was exclusively used for wait_for_completion_timeout so its type is simply adjusted. In img_i2c_xfer an appropriately typed variable is added and assignment fixed up.
