[PATCH v3 0/2] More CONFIG_PM* simplifications

[PATCH v3 0/2] More CONFIG_PM* simplifications

[Bastien Nocera]

Follow-up from the earlier "Bluetooth: btusb: Use pm_ptr instead of
#ifdef CONFIG_PM" patch.

Both drivers were successfully compiled with CONFIG_PM disabled.

Changes since v2:
- Drop btmtksdio.c changes, there's a fix in bluetooth-next

Changes since v1:
- Fix "defined but not used" warnings reported by the kernel test robot
- Modify commit messages following review comments

Bastien Nocera (2):
  Bluetooth: btnxpuart: Remove unneeded CONFIG_PM ifdef
  Bluetooth: btintel: Remove unneeded CONFIG_PM* #ifdef's

[PATCH v3 1/2] Bluetooth: btnxpuart: Remove unneeded CONFIG_PM ifdef

[Bastien Nocera]

The functions are already disabled through the use of pm_ptr() when
CONFIG_PM is disabled, and will be removed from the final linked code
as not needed.

This increases build coverage and allows to drop an #ifdef.

[PATCH v3 2/2] Bluetooth: btintel: Remove unneeded CONFIG_PM* #ifdef's

[Bastien Nocera]

The functions are already disabled if CONFIG_PM or CONFIG_PM_SLEEP are
disabled through the use of SET_SYSTEM_SLEEP_PM_OPS() and
SET_RUNTIME_PM_OPS().

This increases build coverage and allows to drop a few #ifdef's.
