commit f90ec6cdf674248dcad85bf9af6e064bf472b841 upstream
Set memory bandwidth limit to filter out resolutions above 720p@60Hz to
avoid underflow errors due to the bandwidth needs of higher resolutions.
am43xx can not provide enough bandwidth to DISPC to correctly handle
'high' resolutions.

commit 7b2db65b59c30d58c129d3c8b2101feca686155a upstream
24 bits is supported in all modes and 16 bit only when the codec is slave
and the DAI is set to RIGHT_J.
Remove the unsupported sample format.

commit 163be6ff7739b12ff300d77897d340f661821da2 upstream
If a gadget driver is in the pending drivers list, a UDC
becomes available and udc_bind_to_driver() fails, then it
gets deleted from the pending list.
i.e. list_del(&driver->pending) in check_pending_gadget_drivers().
Then if that gadget driver is unregistered,
usb_gadget_unregister_driver() does a list_del(&driver->pending)
again thus causing a page fault as that list entry has been poisoned
by the previous list_del().
Fix this by using list_del_init() instead of list_del() in
check_pending_gadget_drivers().
Test case:
- Make sure no UDC is available
- modprobe g_mass_storage file=wrongfile
- Load UDC driver so it becomes available
lun0: unable to open backing file: wrongfile
- modprobe -r g_mass_storage
