The commit 83ba9ea8 ommitted the return line for the old synaptics model accidentally. This resulted in a wrong check, namely, the dimensions are checked for the old devices that don't support the query properly. This patch adds the return line back.

There are devices out there which are PCI Hot-plug controllers with compaq PCI IDs, but are not bridges, hence have pdev->subordinate NULL. But cpqphp expects the pointer to be non-NULL. Add a check to the probe function to avoid oopses like: BUG: unable to handle kernel NULL pointer dereference at 00000050 IP: [<f82e3c41>] cpqhpc_probe+0x951/0x1120 [cpqphp] *pdpt = 0000000033779001 *pde = 0000000000000000 ...

cb->atapi.cdb is an array of 16 u8 elements. The call too memset() would set the first part of the sge array to zero as well. It's not a packed struct. This one has been around for five years. I found it with Smatch. I think the reason no one has seen it before is because we normally call sil24_fill_sg() and that overwrites sge with proper information?

Since commit cc772ab7 ("gianfar: Add hardware RX timestamping support"), the driver no longer works on at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more boards as well). That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.

With no word size given in the users platform data, a generic spi host controller driver will assume a default word size of eight bit. This causes transmission to be performed bytewise, which will fail on little endian machines for sure. Failure on big endian depends on usage of slave select to mark word boundaries. Anyway, ad7877 is specified to work with 16 bit per word, so unconditionally set the word size accordingly. Flag an error where 16 bit per word is not available.

So when we added output polling, we'd suddenly use this code more often, and the fact that it always takes over crtc2 and messes with it during probing isn't what we really want to be happening. A more complete fix would to change it to use whatever crtc was free at the time, but for now lets stay simple and just don't poll if crtc2 is already in use. Although a more correct fix was found I suspect we should do this as well, until we get a chance to readdres the tv out polling issues.

The vddc value in the power tables is not an actual voltage like on discrete r6xx/r7xx/evergreen systems, but instead has a symbolic meaning (e.g., NONE, LOW, HIGH, etc.).

This adds an additional profile, mid, to the pm profile code which takes the place of the old low profile. The default behavior remains the same, e.g., auto profile now selects between mid and high profiles based on power source, however, you can now manually force the low profile which was previously only available as a dpms off state. Enabling the low profile when the displays are on has been known to cause display corruption in some cases.
