f19910006effbd08398de79ca0233ea7e480616a | Analyze and fix the following issue in the Linux kernel code: autofs: fix thinko in validate_dev_ioctl() | Problem Details:
I was so sure the per-dentry expire timeout patch worked ok but my
testing was flawed.
In validate_dev_ioctl() the check for ioctl AUTOFS_DEV_IOCTL_TIMEOUT_CMD
should use the ioctl number not the passed in ioctl command.

On sdhci_gl9767_set_clock(), the vendor header space(VHS) is read-only
after calling gl9767_disable_ssc_pll() and gl9767_set_ssc_pll_205mhz().
So the low power negotiation mode cannot be enabled again.
Introduce gl9767_set_low_power_negotiation() function to fix it.
