Subject: NFC: trf7970a: Rename TRF7970A_ST_OFF to TRF7970A_ST_RF_OFF
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b5e17d9b5bd7e53696bce21e38eec5b9bb8abb88;p=linux-beck.git

NFC: trf7970a: Rename TRF7970A_ST_OFF to TRF7970A_ST_RF_OFF

Rename the 'TRF7970A_ST_OFF' state to 'TRF7970A_ST_RF_OFF'
to make it clear that this state means that the RF is
off and not the entire device.
