From 96e829b433056d8325916631dc370a4ba42bdaf8 Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Wed, 23 Apr 2014 11:00:55 -0700 Subject: [PATCH] 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 Signed-off-by: Mark A.
