Subject: mmc: atmel-mci: remove data error interrupt after xfer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=abc2c9fdf636c4335a8d72ac3c5ae152bca44b68;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git
mmc: atmel-mci: remove data error interrupt after xfer
Disable data error interrupts while we are actually recording that there
is not such errors. This will prevent, in some cases, the warning message
printed at new request queuing (in atmci_start_request()).
