[PATCH v2 4/4] media: atmel: atmel-isc: make try_fmt error less verbose

From: Eugen.Hristev
Date: Mon Apr 15 2019 - 10:14:11 EST


From: Eugen Hristev <eugen.hristev@xxxxxxxxxxxxx>

In case the sensor refuses to set the format, avoid printing the error
message that no compatible format was found.
This means that the try_fmt will be less verbose.
The error will be printed only if really a format cannot be found.
Some application try all possible formats in a row (gstreamer e.g.)
which will flood the console with error messages until a working one is found.
