Subject: Input: pixcir_i2c_ts - fix receive error
From: Frodo Lai <frodo.lai@xxxxxxxxx>
commit 469d7d22cea146e40efe8c330e5164b4d8f13934 upstream.
The i2c_master_recv() uses readsize to receive data from i2c but compares
to size of rdbuf which is always 27. This would cause problem when the
max_fingers is not 5. Change the comparison value to readsize instead.
Fixes: 36874c7e219 ("Input: pixcir_i2c_ts - support up to 5 fingers and
hardware tracking IDs:)
