[PATCH] staging: r8188eu: do not spam the kernel log

Posted by Michael Straube 3 years, 8 months ago

Drivers should not spam the kernel log if they work properly. Convert
the functions Hal_EfuseParseIDCode88E() and _netdev_open() to use
netdev_dbg() instead of pr_info() so that developers can still enable
it if they want to see this information.
