[ Upstream commit cac7100d4c51c04979dacdfe6c9a5e400d3f0a27 ]

Inside function hideep_nvm_unlock(), variable "unmask_code" could
be uninitialized if hideep_pgm_r_reg() returns error, however, it
is used in the later if statement after an "and" operation, which
is potentially unsafe.

 Input: add support for HiDeep touchscreen 2017-11-10T18:18:22+00:00 Anthony Kim anthony.kim@hideep.com 2017-10-25T21:57:04+00:00 842ff286166e8512450573f6b6eb5e04e626a07f The HiDeep touchscreen device is a capacitive multi-touch controller mainly for multi-touch supported devices use. It use I2C interface for communication to IC and provide axis X, Y, Z locations for ten finger touch through input event interface to userspace. It support the Crimson and the Lime two type IC. They are different the number of channel supported and FW size. But the working protocol is same.
