Subject: Input: ar1021_i2c - fix too long name in driver's device table

From: Dmitry Torokhov <[email protected]>

[ Upstream commit 95123fc43560d6f4a60e74f72836e63cd8848f76 ]

The name field in structure i2c_device_id is 20 characters, and we expect it to be NULL-terminated, however we are trying to stuff it with 21 bytes and thus NULL-terminator is lost. This causes issues when one creates device with name "MICROCHIP_AR1021_I2C" as i2c core cuts off the last "C", and automatic module loading by alias does not work as result.

The -I2C suffix in the device name is superfluous, we know what bus we are dealing with, so let's drop it. Also, no other driver uses capitals, and the manufacturer name is normally not included, except in very rare cases of incompatible name collisions.
