[PATCH 1/2] mmc: sdio: Don't warn about vendor CIS tuples

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



CIS tuples in the range 0x80-0x8F are reserved for vendors. Some devices
have tuples in this range which get warned about every boot. Since this
is normal behavior, don't print these tuples unless debug is enabled.

Unfortunately, we cannot use a variable for the format string since it
gets pasted by pr_*_ratelimited.
