Subject: [PATCH v2 9/9] usb: phy: twl6030: add IRQ checks
Date: Mon, 9 Aug 2021 23:53:16 +0300 [thread overview]
Message-ID: <9507f50b-50f1-6dc4-f57c-3ed4e53a1c25@omp.ru> (raw)
In-Reply-To: <47bacc02-4e34-3208-779c-7072a6261782@omp.ru>
The driver neglects to check the result of platform_get_irq()'s calls and
blithely passes the negative error codes to request_threaded_irq() (which
takes *unsigned* IRQ #), causing them both to fail with -EINVAL, overriding
an original error code. Stop calling request_threaded_irq() with the
invalid IRQ #s.
Fixes: c33fad0c3748 ("usb: otg: Adding twl6030-usb transceiver driver for OMAP4430")
