Subject: [PATCH 6.1 012/164] pwm: Make .get_state() callback return an error code
Date: Wed, 12 Apr 2023 10:32:14 +0200 [thread overview]
Message-ID: <20230412082837.361833267@linuxfoundation.org> (raw)
In-Reply-To: <20230412082836.695875037@linuxfoundation.org>
From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
[ Upstream commit 6c452cff79f8bf1c0146fda598d32061cfd25443 ]
.get_state() might fail in some cases. To make it possible that a driver
signals such a failure change the prototype of .get_state() to return an
error code.
This patch was created using coccinelle and the following semantic patch:
@p1@
identifier getstatefunc;
identifier driver;
@@
struct pwm_ops driver = {
...,
.get_state = getstatefunc
,...
};
@p2@
identifier p1.getstatefunc;
identifier chip, pwm, state;
@@
-void
+int
getstatefunc(struct pwm_chip *chip, struct pwm_device *pwm, struct pwm_state *state)
{
...
- return;
+ return 0;
...
}
plus the actual change of the prototype in include/linux/pwm.h (plus some
manual fixing of indentions and empty lines).
So for now all drivers return success unconditionally. They are adapted
in the following patches to make the changes easier reviewable.
