[Qemu-devel] [PATCH v4 1/2] sdhci: Revert "add optional quirk property to disable card insertion/removal interrupts"

[Andrew Baumann]

This reverts commit 723697551a7e926abe7d3c7f2966012b8075143d.

This change was poorly tested on my part. It squelched card insertion
interrupts on reset, but that was not necessary because sdhci_reset()
clears all the registers (via the call to memset), so the subsequent
sdhci_insert_eject_cb() call never sees the card insert interrupt
enabled. However, not calling the insert_eject_cb results in prnsts
remaining 0, when it actually needs to be updated to indicate card
presence and R/O status.
