ALPM AUX-Wake fast wake sync pulse count is needed by PSR to calculate IO wake and fast wake lines. Convert intel_dp_aux_fw_sync_len as non-static to make it available for PSR code. v2: use int instead of u8 Signed-off-by: Jouni Högander <jouni.hogander@intel.com> --- drivers/gpu/drm/i915/display/intel_dp_aux.c | 2 +- drivers/gpu/drm/i915/display/intel_dp_aux.h | 1 + 2 files changed, 2 insertions(+), 1 deletion(-)
