[Letux-kernel] [PATCH 0/5] Fix SPI module alias for panels used by omapdrm

This patch series fixes a module alias issue with the five recently
added panel drivers used by omapdrm.

Before those panel drivers, omapdrm had custom drivers for the panels,
and prefixed the OF compatible strings with an "omapdss," prefix. The
SPI device IDs are constructed by stripping the OF compatible string
from the prefix, resulting in the "omapdss," prefix being removed, but
the subsequence OF vendor prefix being kept. The SPI drivers thus had
modules aliases that contained the vendor prefix.

Now that the panels are supported by standard drivers and the "omapdss,"
prefix is removed, the SPI device IDs are stripped from the OF vendor
prefix. As the new panel drivers copied the module aliases from the
omapdrm-specific drivers, they contain the vendor prefix in their SPI
module aliases, and are thus not loaded automatically.

Fix this by removing the vendor prefix from the SPI modules aliases in
the drivers. For consistency reason, the manual module aliases are also
moved to use an SPI module table.

These patches are based on the drm-misc-fixes branch as they fix v5.4
