[PATCH} hwmon: (jc42) Properly detect TSE2004-compliant devices again

2024-10-15T02:14:08+00:00

Commit b3e992f69c23 ("hwmon: (jc42)  Strengthen detect function")
attempted to make the detect function more robust for
TSE2004-compliant devices by checking capability bits which, according
to the JEDEC 21-C specification, should always be set. Unfortunately,
not all real-world implementations fully adhere to this specification,
so this change caused a regression.

Stop testing bit 7 (EVSD) of the Capabilities register, as it was
found to be 0 on one real-world device.

Also stop testing bits 0 (EVENT) and 2 (RANGE) as vendor datasheets
(Renesas TSE2004GB2B0, ST STTS2004) suggest that they may not always
be set either.

struct regmap_config is only available if REGMAP is enabled.
Add the missing Kconfig dependency to fix the problem.

hwmon: (adt7475) Fix memory leak in adt7475_fan_pwm_config()

2024-10-07T15:42:31+00:00

The device_for_each_child_node() loop requires calls to
fwnode_handle_put() upon early returns to decrement the refcount of
the child node and avoid leaking memory.

There are multiple early returns within that loop in
adt7475_fan_pwm_config(), but fwnode_handle_put() is never called.
Instead of adding the missing calls, the scoped version of the loop can
be used to simplify the code and avoid mistakes in the future if new
early returns are added.

This issue was recently introduced and it does not affect old kernels
that do not support the scoped variant.

move asm/unaligned.h to linux/unaligned.h

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.
