on XG21. Rearrange the code so that we don't need to set or care about

Joerg Roedel d95abbbb29 staging: zsmalloc: Fix link error on ARM
Testing the arm chromebook config against the upstream
kernel produces a linker error for the zsmalloc module from
staging. The symbol flush_tlb_kernel_range is not available
there. Fix this by removing the reimplementation of
unmap_kernel_range in the zsmalloc module and using the
function directly. The unmap_kernel_range function is not
usable by modules, so also disallow building the driver as a
module for now.

We were setting the DMA masks in dwc2_driver_probe(), but that is
before the driver parameters have been set to their default values.
That meant the DMA masks could be set wrong. Fix it by moving the

have been set.

Matthijs Kooijman 8509f2f43a staging: dwc2: always release host channel after dequeueing
Previously, when an active urb was dequeued, its host channel would
not always be released. There is some special handling for this in
dwc2_hc_chhltd_intr_dma, but when it was the last urb/qtd in its qh, a
safeguard in dwc2_hc_n_intr would short-circuit and prevent the regular
interrupt handlers from running, without releasing the channel.

This is easily triggered when using a 3G modem using the option driver.
Opening and closing any ttyUSBx device will eat up a host channel that
is forever unusable from that point on.

H Hartley Sweeten 100b4edcad staging: comedi: s626: simplify dio register access
This driver has three dio subdevices, each with 16 channels. These
subdevices use hardware registers that are spaced 0x10 bytes apart
for each "group" of 16 channels.

Create new macros to get the correct addresses for each register
based on the dio "group". Use the s->private (void *) to hold the
"group" number to use in the subdevice functions.

This allows removing struct dio_private and all its uses. It also
removes the ugly casts used to get the register address.
