Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.

takes care of both problems. The first patch also makes sure we don't

The dell_rbu driver will use memset() to clear the data held by each
packet when it is no longer needed (when the driver is unloaded, the
packet size is changed, etc).
The amount of memory that is cleared (before this patch) is the normal
packet size. However, the last packet in the list may be smaller.
Fix this to only clear the memory actually used by each packet, to prevent
it from writing past the end of data buffer.
Because the packet data buffers are allocated with __get_free_pages() (in
page-sized increments), this bug could only result in a buffer being
overwritten when a packet size larger than one page is used. The only user
of the dell_rbu module should be the Dell BIOS update program, which uses
a packet size of 4096, so no issues should be seen without the patch, it
just blocks the possiblity.

Pass the correct list head to list_for_each_entry*() when looping through
the packet list.
Without this patch, reading the packet data via sysfs will show the data
incorrectly (because it starts at the wrong packet), and clearing the

If setting up smart PC fails for any reason then this can lead to
a double free when unloading amd-pmf. This is because dev->buf was
freed but never set to NULL and is again freed in amd_pmf_remove().
To avoid subtle allocation bugs in failures leading to a double free
change all allocations into device managed allocations.

The only purpose of the tdc_mask variable is to check whether or not

point, the actual value of the flags do no matter any more because
these can be deduced from some other information.

When the DMA mode is changed on the (still real!) SB AWE32 after
playing a stream and closing, the previous DMA setup was still
silently kept, and it can confuse the hardware, resulting in the
unexpected noises. As a workaround, enforce the disablement of DMA
setups when the DMA setup is changed by the kcontrol.
