mmc: meson-gx: Remove setting of CMD_CFG_ERROR
Browse files Browse the repository at this point in the history
For the t7 and older SoC families, the CMD_CFG_ERROR has no effect.
Starting from SoC family C3, setting this bit without SG LINK data
address will cause the controller to generate an IRQ and stop working.

To fix it, don't set the bit CMD_CFG_ERROR anymore.
