As Christoph said [1],
"vm_map_ram is supposed to generally behave better. So if
it doesn't please report that that to the arch maintainer
and linux-mm so that they can look into the issue. Having
user make choices of deep down kernel internals is just
a horrible interface.
Please talk to maintainers of other bits of the kernel
if you see issues and / or need enhancements. "
Let's redo the previous conclusion and kill the vmap
approach.

As Christoph pointed out [1], "
Why is there __submit_bio which really just obsfucates
what is going on? Also why is __submit_bio using
bio_set_op_attrs instead of opencode it as the comment
right next to it asks you to? "
Let's use submit_bio directly instead.

"Why is there __erofs_get_meta_page with the two weird

for additional bio op flags."
And since all callers can handle errors, let's kill
prio and nofail and erofs_get_inline_page() now.

In case of a missing (optional) gpio don't fall through up to
"ti,active-discharge-time-us" due to
devm_fwnode_get_index_gpiod_from_child() returning NULL (since
gpiod_get_from_of_node() returned NULL) but rather indicate success as
intended.
This makes the driver probe correctly when e.g. only the enable gpio is
given.

The g12a audio subsystem, which is a derivative of the axg subsystem,
provides a dedicated reset line for each of the audio components.
The axg did not provide that and it is unclear if/when these reset are
required. The reset already helped solve a channel mapping issue on the
tdm formatter devices. Let's add the reset binding for the other
components, so we can describe this in DT. We'll use it later on
in the driver when/if needed.

Tiger Lake has up to 4 pipes so the mask would need to be 0xf instead of
0x7. Do not hardcode the mask so it allows the fake MST encoders to
connect to all pipes no matter how many the platform has.
Iterating over all pipes to keep consistent with intel_ddi_init().
Initialy this patch was replaced by commit 4eaceea3a0 ("drm/i915:
Fix DP-MST crtc_mask") but userspace it not correctly using
encoder.possible_crtcs and it was reverted by
commit e838bfa8e1 ("Revert "drm/i915: Fix DP-MST crtc_mask"")
Userspace should be fixed but it might take a while, so bringing this
patch back for now.
