| Subject: Input: pixcir_i2c_ts - fix receive error |
| |
| From: Frodo Lai <frodo.lai@gmail.com> |
| |
| 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:) |
