Subject: Fix AUTOFS_DEV_IOCTL_REQUESTER_CMD
X-Git-Tag: MMI-PSA29.97-13-9~28392^2~18
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf2706a340ae98616d4e2a54900393e0e0b6b72c;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

Fix AUTOFS_DEV_IOCTL_REQUESTER_CMD

Missing conversion from kernel to userland dev_t; this sucker
breaks as soon as we get sufficiently many autofs mounts for
new_encode_dev(s_dev) != s_dev.

Note: this is the minimal fix.
