From f2602fba4723e408380eb9a56e921d36a1ae21f8 Mon Sep 17 00:00:00 2001 From: Simon Trimmer Date: Mon, 22 Apr 2024 11:32:11 +0100 Subject: ASoC: cs35l56: Avoid static analysis warning of uninitialised variable Static checkers complain that the silicon_uid variable passed by pointer to cs35l56_read_silicon_uid() could later be used uninitialised when calling cs_amp_get_efi_calibration_data(). cs35l56_read_silicon_uid() must have succeeded to call cs_amp_get_efi_calibration_data() and that would have populated the variable. However, initialise the value so we are not haunted by it forevermore.
