Subject: Input: mpu3050 - ensure we enable interrupts
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3b5187248bd07e400af081ad777e9aa1e5519ad7;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

Input: mpu3050 - ensure we enable interrupts

This also changes the devname parameter delivered to
request_threaded_irq() from "mpu_int" to "mpu3050".
