Dmitry Torokhov 9891b528f9 Input: synaptics - avoid using uninitialized variable when probing 
commit f39f868888 upstream.

synaptics_detect() does not check whether sending commands to the
device succeeds and instead relies on getting unique data from the
device. Let's make sure we seed entire buffer with zeroes to make sure
we will not use garbage on stack that just happen to be 0x47.
