 The ``power_save`` option is exported as writable.  This means you can
 adjust the value via sysfs on the fly.  For example, to turn on the
 automatic power-save mode with 10 seconds, write to

 Note that you might hear click noise/pop when changing the power
 state.  Also, it often takes certain time to wake up from the
-power-down to the active state.  These are often hardly to fix, so
+power-down to the active state.  These are often hard to fix, so
 don't report extra bug reports unless you have a fix patch ;-)
