mmc: longer timeout for long read time quirk
commit 32ecd320db39bcb007679ed42f283740641b81ea upstream.
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.
() Add this specific MMC to the quirk
