It is impossible for debugfs_create_dir() to return NULL, so checking
for it gives people a false sense that they actually are doing something
if an error occurs. As there is no need to ever change kernel logic if
debugfs is working "properly" or not, there is no need to check the
return value of debugfs calls, so remove the checks here as they will
never be triggered and are wrong.

The driver core ignores the return value of struct bus_type::remove()
because there is only little that can be done. To simplify the quest to
make this function return void, let struct vio_driver::remove() return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error code is a bad idea.
Note there are two nominally different implementations for a vio bus:
one in arch/sparc/kernel/vio.c and the other in
arch/powerpc/platforms/pseries/vio.c. This patch only adapts the powerpc
one.
Before this patch for a device that was bound to a driver without a
remove callback vio_cmo_bus_remove(viodev) wasn't called. As the device
core still considers the device unbound after vio_bus_remove() returns
calling this unconditionally is the consistent behaviour which is
implemented here.

Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates

- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

Only one change in this pull, but it's required for other things, so it
needs to go in.

Merge tag 'tpmdd-next-v5.12-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd
Pull tpm updates from Jarkko Sakkinen:
"New features:
- Cr50 I2C TPM driver
- sysfs exports of PCR registers in TPM 2.0 chips
Bug fixes:
- bug fixes for tpm_tis driver, which had a racy wait for hardware
state change to be ready to send a command to the TPM chip. The bug
has existed already since 2006, but has only made itself known in
recent past. This is the same as the "last time" :-)
- Otherwise there's bunch of fixes for not as alarming regressions. I
think the list is about the same as last time, except I added fixes
for some disjoint bugs in trusted keys that I found some time ago"
