[v6,25/57] media: Remove dev_err() usage after platform_get_irq()

Commit Message

Stephen Boyd July 30, 2019, 6:15 p.m. UTC

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).

Looks like this didn't catch the double assignments in:

drivers/media/platform/rcar_fdp1.c:     fdp1->irq = ret =
platform_get_irq(pdev, 0);
drivers/media/platform/rcar_fdp1.c-     if (ret < 0) {
drivers/media/platform/rcar_fdp1.c-             dev_err(&pdev->dev,
"cannot find IRQ\n");
drivers/media/platform/rcar_fdp1.c-             return ret;
drivers/media/platform/rcar_fdp1.c-     }
drivers/media/platform/rcar_fdp1.c-
--
drivers/media/platform/rcar_jpu.c:      jpu->irq = ret =
platform_get_irq(pdev, 0);
drivers/media/platform/rcar_jpu.c-      if (ret < 0) {
drivers/media/platform/rcar_jpu.c-              dev_err(&pdev->dev,
"cannot find IRQ\n");
drivers/media/platform/rcar_jpu.c-              return ret;
drivers/media/platform/rcar_jpu.c-      }
drivers/media/platform/rcar_jpu.c-
