Subject: [media] coda: Propagate the correct error on devm_request_threaded_irq()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=08c8d14e7507d318cbd6ecae2c6c7cb31d0037af;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] coda: Propagate the correct error on devm_request_threaded_irq()

If devm_request_threaded_irq() fails, we should better propagate the real error.

Also, print out the error code in the dev_err message.
