Merge branch 'pm-runtime'

Merge updates related to runtime PM for 6.20-rc1/7.0-rc1:

 - Make several drivers discard pm_runtime_put() return value in
   preparation for converting that function to a void one (Rafael
   Wysocki)

* pm-runtime:
  drm: Discard pm_runtime_put() return value
  genirq/chip: Change irq_chip_pm_put() return type to void
  scsi: ufs: core: Discard pm_runtime_put() return values
  platform/chrome: cros_hps_i2c: Discard pm_runtime_put() return value
  coresight: Discard pm_runtime_put() return values
  hwspinlock: omap: Discard pm_runtime_put() return value
  watchdog: rzv2h_wdt: Discard pm_runtime_put() return value
  watchdog: rz: Discard pm_runtime_put() return values
  media: ccs: Discard pm_runtime_put() return value
  drm/imagination: Discard pm_runtime_put() return value
  USB: core: Discard pm_runtime_put() return value
