Subject: max17042_battery: Handle irq request failure case
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e5ba50bc3b9311256ae6a6620e7708fb25d1f6e2;p=linux-beck.git

max17042_battery: Handle irq request failure case

suspend/resume functions take action based upon the fuel gauge
interrupt. If the rquest irq fails we should assign 0 to client->irq.
