NFC: digital: SENSF_RES excludes RD when SENSF_REQ RC is zero
The check in digital_tg_send_sensf_res() that excludes the 'RD' field from the SENSF_RES is inverted. The 'RD' field should be excluded when the SENSF_REQ 'RC' field is equal to DIGITAL_SENSF_REQ_RC_NONE instead of when its not equal. This is described in section 6.6.2.11 of the NFC Digital Specification. CC: Thierry Escande <thierry.escande@linux.intel.com> Signed-off-by: Mark A.
