[PATCH V2, 1/1] media: mc-device.c: change media_device_request_alloc to match media_ioctl_info

[frederic.chen at mediatek.com]

From: Frederic Chen <frederic.chen at mediatek.com>

We modified the type of media_device_request_alloc()'s second
parameter from int* to void* so that it can match the interface
defined in struct media_ioctl_info.
