From: Tomohiro Kusumi <tkusumi@xxxxxxxxxx> Subject: autofs: use unsigned int/long instead of uint/ulong for ioctl args The standard types unsigned int and unsigned long should be used for .compat_ioctl. autofs is the only fs using uing/ulong for this, and these are even the only uint/ulong in the entire autofs code. Drop unneeded long cast in return value of autofs_dev_ioctl_compat(). It's already long.
