Subject: [PATCH v2 1/2] mmc/host/rtsx: Configure SD_CFG2 register in sd_rw_multi
From: Wei WANG <wei_wang@...lsil.com.cn>
For Realtek card reader, internal regsiter SD_CFG2 should be configured
before transferring data. In the prior version, the value of this register
has been calculated, but forgotten to write back to the internal register.
