Input: goodix - check the 'buffer status' bit before reading data
The MSB of the first byte read via I2C at the coordinates address indicates whether the data is valid or ready (called "buffer status" in the datasheets) when an interrupt is raised. Previously, this bit was ignored, which resulted in a lot of incorrect detections of "finger removed" events. Signed-off-by:Paul Cercueil <paul@crapouillou.net> Acked-by:
