From 32ecd320db39bcb007679ed42f283740641b81ea Mon Sep 17 00:00:00 2001 From: Matt Gumbel Date: Fri, 20 May 2016 10:33:46 +0300 Subject: mmc: longer timeout for long read time quirk 008GE0 Toshiba mmc in some Intel Baytrail tablets responds to MMC_SEND_EXT_CSD in 450-600ms. This patch will... () Increase the long read time quirk timeout from 300ms to 600ms. Original author of that quirk says 300ms was only a guess and that the number may need to be raised in the future.
