From b876eb87e91d6705ef946090af16175dfb5ce1f9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 25 Sep 2021 07:03:11 -0600 Subject: [PATCH] image: Avoid switch default in image_decomp() At present this function is full of preprocessor macros. Adjust it to check for an unsupported algorithm after the switch(). This will allow us to drop the macros. Fix up the return-value path and an extra blank line while we are here.
