Subject: ath10k: print errcode when CE ring setup fails
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ba7ee55f8c10e07dd15dbfd7ac20a300bb673316;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ath10k: print errcode when CE ring setup fails

This makes it possible to see the reason why the
setup fails. It also adheres to code style of
error checking in ath drivers.
