From: Tim Sell Date: Thu, 9 Jul 2015 17:27:44 +0000 (-0400) Subject: staging: unisys: prevent faults in visornic_pause X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5deeea3379b2fc34d07cfb909b2905e9e1116615;p=linux-beck.git staging: unisys: prevent faults in visornic_pause Prevent faults in visornic_pause, visornic_resume(), and visornic_remove() Prior to this patch, any call to visornic_pause(), visornic_resume(), or visornic_remove() would fault, due to dev_set_drvdata() never having been called to stash our struct visornic_devdata * into the device's drvdata. I.e., all calls to dev_get_drvdata() were returning NULL, meaning a fault was soon to follow.
