[PATCH] input: ili210x: Fix uninitialized symbols in ili251x_firmware_to_buffer

[Purva Yeshi <purvayeshi550@gmail.com>]

Fix Smatch-detected issue:

drivers/input/touchscreen/ili210x.c:621 ili251x_firmware_to_buffer()
error: uninitialized symbol 'fw_addr'.
drivers/input/touchscreen/ili210x.c:621 ili251x_firmware_to_buffer()
error: uninitialized symbol 'fw_len'.

Initialize 'fw_addr' and 'fw_len' to 0 in ili251x_firmware_to_buffer()
to avoid uninitialized use warnings reported by smatch.

Although the while loop ensures both variables are always assigned before
use, initializing them silences false positives.
