The i2c_master_recv() uses readsize to receive data from i2c but compares to size of rdbuf which is always 27. This would casue problem when the max_fingers is not 5. Change the comparison value to readsize instead. Signed-off-by: Frodo Lai <frodo_lai@bcmcom.com> --- drivers/input/touchscreen/pixcir_i2c_ts.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
