Subject: [PATCH v2 02/12] mmc: meson-gx: fix deferred probing
Date: Thu, 8 Jun 2023 22:45:09 +0300 [thread overview]
Message-ID: <20230608194519.10665-3-s.shtylyov@omp.ru> (raw)
In-Reply-To: <20230608194519.10665-1-s.shtylyov@omp.ru>
The driver overrides the error codes and IRQ0 returned by platform_get_irq()
to -EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the error
codes upstream. IRQ0 is no longer returned by platform_get_irq(), so we now
can safely ignore it...
Fixes: cbcaac6d7dd2 ("mmc: meson-gx-mmc: Fix platform_get_irq's error checking")
Signed-off-by: Sergey Shtylyov <s.shtylyov@omp.ru>

Changes in version 2:
- updated the fix due to the surrounding code change;
- refreshed the patch;
- removed stray newline in the Fixes: tag;
- slightly reformatted the patch description.
