Subject: [PATCH 0/2] Changes for pwmchip_remove()
Date: Wed, 24 Mar 2021 16:20:56 +0100	[thread overview]
Message-ID: <20210324152058.69022-1-u.kleine-koenig@pengutronix.de> (raw)

pwmchip_remove currently can (theoretically) return an error code and
most drivers check for that and pass an error to the upper layer just to
be ignored there. Before device links were used this resulted in
half-registered drivers that failed to free all allocated resources.
Today it just makes these remove functions more complicated than
necessary.

This series simplifies pwmchip_remove() and prepares a first driver to
eventually make pwmchip_remove() return void.

Best regards
Uwe

  pwm: Drop unused error path from pwmchip_remove()
  pwm: imx27: Don't check the return code of pwmchip_remove()
