Subject: [PATCH] counter: 104-quad-8: Fix race getting function mode and
direction
The quad8_action_read() function checks the Count function mode and
Count direction without first acquiring a lock. This is a race condition
because the function mode could change by the time the direction is
checked.
Because the quad8_function_read() already acquires a lock internally,
the quad8_function_read() is refactored to spin out the no-lock code to
a new quad8_function_get() function.
To resolve the race condition in quad8_action_read(), a lock is acquired
before calling quad8_function_get() and quad8_direction_read() in order
to get both function mode and direction atomically.

Subject: [PATCH] mmc: sdhci-pci-core: Disable ES for ASUS BIOS on Jasper Lake
Enhanced Strobe (ES) does not work correctly on the ASUS 1100 series of
devices. Jasper Lake eMMCs (pci_id 8086:4dc4) are supposed to support
ES. There are also two system families under the series, thus this is
being scoped to the ASUS BIOS.
The failing ES prevents the installer from writing to disk. Falling back
to HS400 without ES fixes the issue.

Subject: [PATCH] mmc: sdhci-pci-core: Disable ES for ASUS BIOS on Jasper Lake
Enhanced Strobe (ES) does not work correctly on the ASUS 1100 series of
devices. Jasper Lake eMMCs (pci_id 8086:4dc4) are supposed to support
ES. There are also two system families under the series, thus this is
being scoped to the ASUS BIOS.
The failing ES prevents the installer from writing to disk. Falling back
to HS400 without ES fixes the issue.
