Subject: tools:iio:generic_buffer: pass up right error code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e83a47cf6a5bdbd3d5677db13ae4df22f5e24b08;p=linux-beck.git

tools:iio:generic_buffer: pass up right error code

find_type_by_name() returns a valid error code in case of an error. Pass
this code up instead of an artificial one.
