Subject: Staging: ced1401: usb1401: fix build errors.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6ede1edea3e7632e50a4b86165112d6364cdadb6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Staging: ced1401: usb1401: fix build errors.

This fixes up the usb1401.c file to remove the usage of err() (which is
gone), and the two-argument kmap_atomic() call, and the compat_ioctl
pointer warning.

The code now builds properly, there are lots of warnings still, but it's
a start.
