Subject: Input: elants_i2c - zero-extend hardware ID in firmware name
X-Git-Tag: v4.1-rc1~57^2^2~4

Input: elants_i2c - zero-extend hardware ID in firmware name

Let's zero-extend hardware id number when forming firmware file name,
to avoid kernel requesting firmware like "elants_i2c_   0.bin", which
is quite unexpected.
