It is possible to turn off the card clock by setting the frequency to zero via debugfs e.g. echo 0 > /sys/kernel/debug/mmc0/clock However that produces an incorrect warning that is designed to warn if the frequency is below the minimum operating frequency. So correct the warning. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> --- drivers/mmc/core/core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
