Re: [PATCHv4 07/10] fbdev: ssd1307fb: Add a module parameter to set the refresh rate

This patch adds the module parameter "refreshrate" to set delay for the
deferred io. The refresh rate is given in units of Hertz. The default
refresh rate is 1 Hz. The refresh rate set through the newly introduced
parameter applies to all instances of the driver and for now it is not
possible to change it individually.
