Subject: ice: Use common error handling code in two functions
X-Git-Tag: v6.13-rc1~135^2~364^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5f4493f06e81e0de5a22cbf0ae4ead7a3037208e;p=thirdparty%2Fkernel%2Flinux.git

ice: Use common error handling code in two functions

Add jump targets so that a bit of exception handling can be better reused
at the end of two function implementations.

This issue was detected by using the Coccinelle software.
