The include/media/s5p_fimc.h header has been removed in commit
49b2f4c5 ("exynos4-is: Remove support
for non-dt platforms"). This broke compilation of the m5mols driver.

Include the include/media/exynos-fimc.h header instead, which contains
the S5P_FIMC_TX_END_NOTIFY definition required by the driver.

Change the I/O endpoint handling of the mceusb driver to respect the endpoint
type reported by device (bulk/interrupt), rather than treating all endpoints
as type interrupt, which breaks devices using bulk endpoints when connected
to a xhci controller.  Accordingly, change the function calls to initialize
an endpoint's transfer pipe and urb handlers to use the correct function based
on the endpoint type.

Currently stk1160_read_reg() uses a stack-allocated char to get the
read control value. This is wrong because usb_control_msg() requires
a kmalloc-ed buffer.

This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive
the read value.

While here, let's remove the urb_buf array which was meant for a similar
purpose, but never really used.
