The printers in dp_mst are meant to be gated on DRM_UT_DP, so use the
debug category printer to avoid dumping mst transactions to the wrong
place.

This patch adds a new module parameter called drm.trace which accepts

This patch adds a new printer which will select the appropriate output

In preparation for tracefs support, rename drm_debug related functions
to reflect that it targets the syslog. This will allow us to selectively
target syslog and/or tracefs.

The ti_sn_bridge_gpio_set() got the return value of
regmap_update_bits() but didn't check it. The function can't return
an error value, but we should at least print a warning if it didn't
work.
This fixes a compiler warning about setting "ret" but not using it.
