[PATCH v2 0/2] platform/x86: thinkpad_acpi: cleanup conversions

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

This series converts thinkpad_acpi resource management to use helpers
from linux/cleanup.h:
- Convert conditional mutex lock calls to ACQUIRE() and ACQUIRE_ERR()
- Use __free(kfree) for local pointer allocations

Changes in v2:
- Dropped patch 1 ("convert mutex_lock() to guard(mutex)") as it was
  already applied upstream.
- Preserved 0 return value on failure in brightness_get().
- Fixed auxmac_init() to avoid setting auxmac to "unavailable" before
  evaluating the MACA ACPI method.
- Collected Reviewed-by and Tested-by trailers.
