media: hantro: add fallback handling for single irq/clk

Currently the driver expects that each irq/clk will have a name
specified.

A valid point was raised by the DT maintainers - when there is a single
interrupt line or clock - the names are not needed.

Keep the names within the drivers themselves, but don't use them when
only a single entry exists. Instead use:
 - num_clk == 1 - devm_clk_get(..., NULL)

media: pvrusb2: fix warning in pvr2_i2c_core_done

syzbot has reported the following warning in pvr2_i2c_done:

sysfs group 'power' not found for kobject '1-0043'

When the device is disconnected (pvr_hdw_disconnect), the i2c adapter is
not unregistered along with the USB and v4l2 teardown. As part of the USB
device disconnect, the sysfs files of the subdevices are also deleted.
So, by the time pvr_i2c_core_done is called by pvr_context_destroy, the
sysfs files have been deleted.

To fix this, unregister the i2c adapter too in pvr_hdw_disconnect. Make
the device deregistration code shared by calling pvr_hdw_disconnect from
pvr2_hdw_destroy.

media: I2C: change 'RST' to "RSET" to fix multiple build errors

The use of an enum named 'RST' conflicts with a #define macro
named 'RST' in arch/mips/include/asm/mach-rc32434/rb.h.

The MIPS use of RST was there first (AFAICT), so change the
media/i2c/ uses of RST to be named 'RSET'.
'git grep -w RSET' does not report any naming conflicts with the
new name.

This fixes multiple build errors:

This is used among other things for setting the HPD output pin.

media: exynos-gsc: fix pm_runtime_get_sync() usage count

The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.
Replace it by the new pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
in order to properly decrement the usage counter, avoiding
a potential PM usage counter leak.

As a bonus, as pm_runtime_get_sync() always return 0 on
success, the logic can be simplified.

The pm_runtime_get_sync() internally increments the

On some places, this is ok, but on others the usage count

As a bonus, such function always return zero on success. So,

media: sti/bdisp: fix pm_runtime_get_sync() usage count

The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.

The bdisp_start_streaming() doesn't take it into account, which
would unbalance PM usage counter at bdisp_stop_streaming().

The logic at bdisp_probe() is correct, but the best is to use
the same call along the driver.

So, replace it by the new pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
