Subject: iio: mcp9600: switch to using FIELD_GET_SIGNED()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1af735749f5d6470742192ec06f57f9e28aee614;p=thirdparty%2Fkernel%2Flinux.git

iio: mcp9600: switch to using FIELD_GET_SIGNED()

Switch from sign_extend32(FIELD_GET()) to the dedicated
FIELD_GET_SIGNED() and don't calculate the fields length explicitly.
