Subject: media: ov2740: Debug log chip ID
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=47601552499d48a3c309545f857bd797baaf6aaf;p=users%2Fjedix%2Flinux-maple.git

media: ov2740: Debug log chip ID

Calling the identify function may get delayed till the first stream-on,
add a dev_dbg() to it so that we know when it has run. This is useful
to debug bring-up problems related to regulators / clks / GPIOs.
