From 23d1d10c4248f1b9f838e512e7f18e600f06b348 Mon Sep 17 00:00:00 2001 From: Bo Shen Date: Fri, 19 Sep 2014 14:15:12 +0800 Subject: [PATCH] usb: gadget: fastboot: improve download progress bar When download is ongoing, if the actual size of one transfer is not the same as BYTES_PER_DOT, which will cause the dot won't print anymore. Then it will let the user thinking it is stuck, actually it is transfering without dot printed. So, improve the method to show the progress bar (print dot).
