Subject: HID: hidraw: add compatibility ioctl() for 32-bit applications.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ae5e49c79c051ea1d5ca91cbd4a0d22189067ba3;p=linux-beck.git

HID: hidraw: add compatibility ioctl() for 32-bit applications.

Added the ioctl function to the compat_ioctl pointer in the file_operations
struct. Before this, some ioctls would fail for 32-bit apps on 64-bit systems.
