Originally retry could happen only at index 0 when first indirect node
installed:
in this case tags holds only 1 bit. Seems like now this happends at any index.

The purpose of this series is to add the driver for Media Data Path HW embedded
in the Mediatek's MT8173 SoC.
MDP is used for scaling and color space conversion.
It could convert V4L2_PIX_FMT_MT21 to V4L2_PIX_FMT_NV12M or
V4L2_PIX_FMT_YUV420M.

In case of error, the function dma_request_chan() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().

Sometimes we need to debug during hibernation resume stage, and
it would be convenient for the user to test if the snapshot stored

is useful to ease the debugging process on hibernation,
since this mode can not only bypass the BIOSes/bootloader,

In function 'xilinx_pcie_init_irq_domain', the pattern used to check and
return error is:
if (!var) {
dev_err(...);
return PTR_ERR(var);
}
So the returned value in case of error is always 0, which means 'success'.
Change it to return -ENODEV instead.

Bugger, that doesn't actually work. IS_BUILTIN expects the symbol to be

Turned on that driver->owner which is struct module is not available when
modules are disabled. Better to depend on a driver name which is
always available.

Including devlink.h on ARM and probably other 32-bit architectures results in
a harmless warning:

This will be useful when the condition becomes slightly more
