X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1926a27299db00239d6bdc4c3f2bd3f842277d0d;p=linux.git

wifi: rtw88: debug: add to check if debug mask is enabled

The coming dump function for FW malfunction will add a function to
dump registers to reflect status. However, if we are not debugging
the mechanism, we don't print anything, so avoid reading registers by
checking debug mask to reduce IO.
