Subject: iio: adc: ad7606_spi: use bitmap_full() in ad7606_spi_update_scan_mode()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e44c635ba8c281f74001d47e20bbcb7f516530c;p=thirdparty%2Flinux.git

iio: adc: ad7606_spi: use bitmap_full() in ad7606_spi_update_scan_mode()

bitmap_full() is less verbose and more efficient, as it stops traversing
scan_mask as soon as the 1st unset bit found.
