Subject: [PATCH 1/2] media: usb: dvb-usb-v2: af9035: report if i2c client isn't bound
Date: Sat, 12 Jun 2021 11:13:50 +0200 [thread overview]
Message-ID: <20210612091351.7169-1-uwe@kleine-koenig.org> (raw)
If a sub device doesn't immediately bind after it was added, emit an
error indication to the kernel log to help debugging. This happens for
example if the needed driver isn't available at all.
