Since commit 141f15c66d94 ("leds: pwm: remove header") that platform
interface is not usable from outside and there seems to be no in tree
user anymore. All in-tree users of the leds-pwm driver seem to use DT
currently. Getting rid of the old platform interface will allow the
leds-pwm driver to
Hei hei,
for leds-gpio you can use the properties 'function' and 'color' in the
devicetree node and omit 'label', the label is constructed
automatically. This is a common feature supposed to be working for all
LED drivers. However it did not yet work for the 'leds-pwm' driver.

If LEDs are configured through device tree and the property 'label' is
omitted, the label is supposed to be generated from the properties
'function' and 'color' if present. While this works fine for e.g. the
'leds-gpio' driver, it did not for 'leds-pwm'.
The reason is, you get this label naming

The example was adapted slightly to make use of the 'function' and
'color' properties. License discussed with the original author.

The variable ret has been initialized with '-ENOMEM'. The assignment
in the if branch is redundant. So remove it.

Not that I can tell.
Obviously all allocators tend to have their own alignment concerns, so
they'll all align things up internally anyway.

When budget is non-zero, skb_unref() has already handled the
NULL checking.
When budget is zero, the dev_consume_skb_any() has handled NULL
checking in __dev_kfree_skb_irq(), or dev_kfree_skb() which also
ultimately call skb_unref().
So remove the unnecessary checking in napi_consume_skb().

mhi_fw_load_sbl() function is currently used to transfer SBL or EDL
images over BHI (Boot Host Interface). Same goes with mhi_fw_load_amss()
which uses BHIe. However, the contents of these functions do not
indicate support for a specific set of images. Since these can be used
for any image
In some cases, the entry of device to RDDM execution environment
can occur after a significant amount of time has elapsed after the
SYS_ERROR state change event has arrived. This can result in scenarios
where users of the MHI bus are unaware of the error state of the
device. Hence, moving the MHI
If MHI were to attempt a device shutdown following an assumption
that the device is inaccessible, the host currently moves to a state
where device register accesses are allowed when they should not be.
This would end up allowing accesses to the device register space when
the link is inaccessible
Move MHI to a firmware download error state for a failure to find
the firmware files or to load SBL or EBL image using BHI/BHIe. This
helps detect an error state sooner and shortens the wait for a
synchronous power up timeout.

MHI clients can request a device wake even if the device may be in an
error state or undergoing shutdown. To prevent unnecessary device wake
processing, check for the device state and bail out early so that the
clients are made aware of the device state sooner.

MHI work is currently scheduled on the global/system workqueue and can
encounter delays on a stressed system. To avoid those unforeseen
delays which can hamper bootup or shutdown times, use a dedicated high
priority workqueue instead of the global/system workqueue.

Remove the IRQF_SHARED flag as it is not needed for the BHI interrupt
and replace it with IRQF_ONESHOT so that host can be sure that the
next BHI hard interrupt is triggered only when the threaded interrupt
handler has returned. This is to avoid any race conditions we may run
into if BHI
If the host receives a mission mode event and by the time it can get
to processing it, the register accesses fail implying a connectivity
error, MHI should move to an error state. This helps avoid longer wait
times from a synchronous power up perspective and accurately reflects
the MHI execution
Bug fixes and improvements for MHI powerup and shutdown handling.
Firmware load function names are updated to accurately reflect their purpose.
Closed certain design gaps where the host (MHI bus) would allow clients to
operate after a power down or error detection.
