[PATCH] Input: iqs626a - Use common error handling code in iqs626_parse_events()

From: Markus Elfring
Date: Sat Mar 02 2024 - 06:42:48 EST

Add a jump target so that a bit of exception handling can be better reused
at the end of this function implementation.

This issue was transformed by using the Coccinelle software.
