Subject: [PATCH v6 27/57] mfd: Remove dev_err() usage after platform_get_irq()
Date: Tue, 30 Jul 2019 11:15:27 -0700	[thread overview]
Message-ID: <20190730181557.90391-28-swboyd@chromium.org> (raw)
In-Reply-To: <20190730181557.90391-1-swboyd@chromium.org>

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>

While we're here, remove braces on if statements that only have one
statement (manually).
