spi: make remove callback a void function
...
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

drm/panel: db7430: Add driver for Samsung DB7430
...
This adds a new driver for the Samsung DB7430 DPI display
controller as controlled over SPI.
Right now the only panel product we know that is using this
display controller is the LMS397KF04 but there may be more.
This is the first regular panel driver making use of the
MIPI DBI helper library. The DBI "device" portions can not
be used because that code assumes the use of a single
regulator and specific timings around the reset pulse that
do not match the DB7430 datasheet.
