UPSTREAM: drm/edid: Extract SADs properly from multiple audio data blocks
SADs may span multiple CEA audio data blocks in the EDID.
CEA-861-E says:
"The order of the Data Blocks is not constrained. It is also possible
to have more than one of a specific type of data block if necessary to
include all of the descriptors needed to describe the sink’s capabilities."
Each audio data block can carry up to 10 SADs, whereas the ELD SAD limit
is 15 according to HDA 1.0a spec. So we should support at least two data
blocks. And apparently some devices take a more liberal interpretation
and stuff only one SAD per data block even when they would fit into one.
So let's try to extract all the SADs we can fit into the ELD even when
they span multiple data blocks.
While at it, toss in a comment to explain the 13 byte monitor name
string limit which confused me at first.

UPSTREAM: PM / devfreq: rk3399_dmc: Fix module autoload
If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/devfreq/rk3399_dmc.ko | grep alias

Current code uses devm_regulator_get() in .probe so a regulator_put() will
