Subject: wil6210: unify wmi_set_ie() error handling
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5421bf0c1e37642f42758fe1c73e43b27901dd61;p=linux-beck.git

wil6210: unify wmi_set_ie() error handling

When printing error message, provide string describing IE kind.
Derive it from IE type
This allows removing of error messages printing
in callers
