commit 433e2802775c370604b74378c00977b86623fa12
|
|
category: feature
|
|
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EMQV
|
|
CVE: NA
|
|
|
|
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=433e2802775c370604b74378c00977b86623fa12

----------------------------------------------------------------------
|
|
|
|
To improve code readability and maintainability, refactor
|
|
hclgevf_cmd_convert_err_code() with an array of imp_errcode
|
|
and common_errno mapping, instead of a bloated switch/case.
