According to the standard count 0 is special - no IO should happen but we can check error conditions (device gone away, etc), and return 0 if there are no errors. We used to return -EINVAL instead and we also could return 0 if an event was "stolen" by another thread. Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

When copy_to/from_user fails in the middle of transfer we should not report to the user that read/write partially succeeded but rather report -EFAULT right away, so that application will know that it got its buffers all wrong. If application messed up its buffers we can't trust the data fetched from userspace and successfully written to the device or if data read from the device and transferred to userspace ended up where application expected it to end. If serio_write() fails we still going to report partial writes if failure happens in the middle of the transfer. This is basically a revert of 7a0a27d2 and 4fa07711.

Commit c79396c1 ("mmc: sdhci: prevent card detection activity for non-removable cards") disables card detection where the cards are marked as non-removable. This makes sense, but the implementation detail of calling mmc_card_is_removable() causes some problems, because mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root filesystem is stored on SD, but we also have external SD card slots where we want automatic card detection. Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE, which is defined to mean that the card is *really* nonremovable. This could be revisited in future if we find a way to improve CONFIG_MMC_UNSAFE_RESUME semantics.
