From ee145f66e77ac89cc8d98550a14b9972daf22925 Mon Sep 17 00:00:00 2001 From: Zhenyu Wang Date: Mon, 14 Nov 2016 10:32:58 +0800 Subject: [PATCH] drm/i915/gvt: Fix static checker warning on intel_gvt_i2c_handle_aux_ch_write() Static checker gave warning on: drivers/gpu/drm/i915/gvt/edid.c:506 intel_gvt_i2c_handle_aux_ch_write() warn: odd binop '0x0 & 0xff' We try to return ACK for I2C reply which is defined with 0. Remove bit shift which caused misleading bit op.
