Since we have a little function to see whether a channel
program address falls within a range of CCWs, let's use
it in the other places of code that make these checks.
(Why isn't ccw_head fully removed? Well, because this
way some longs lines don't have to be reflowed.)

The routine ccwchain_calc_length() is tasked with looking at a
channel program, seeing how many CCWs are chained together by
the presence of the Chain-Command flag, and returning a count
to the caller.
Previously, it also considered a Transfer-in-Channel CCW as being
an appropriate mechanism for chaining. The problem at the time
was that the TIC CCW will almost certainly not go to the next CCW
in memory (because the CC flag would be sufficient), and so
advancing to the next 8 bytes will cause us to read potentially
invalid memory. So that comparison was removed, and the target
of the TIC is processed as a new chain.
This is fine when a TIC goes to a new chain (consider a NOP+TIC to
a channel program that is being redriven), but there is another
scenario where this falls apart. A TIC can be used to "rewind"
a channel program, for example to find a particular record on a
disk with various orientation CCWs. In this case, we DO want to
consider the memory after the TIC since the TIC will be skipped
once the requested criteria is met. This is due to the Status
Modifier presented by the device, though software doesn't need to
operate on it beyond understanding the behavior change of how the
channel program is executed.
So to handle this, we will re-introduce the check for a TIC CCW
but limit it by examining the target of the TIC. If the TIC
doesn't go back into the current chain, then current behavior
applies; we should stop counting CCWs and let the target of the
TIC be handled as a new chain. But, if the TIC DOES go back into
the current chain, then we need to keep looking at the memory after
the TIC for when the channel breaks out of the TIC loop. We can't
use tic_target_chain_exists() because the chain in question hasn't
been built yet, so we will redefine that comparison with some small
functions to make it more readable and to permit refactoring later.

It was reported that some devices report an OPTIMAL TRANSFER LENGTH of
0xFFFF blocks. That looks bogus, especially for a device with a
4096-byte physical block size.
Ignore OPTIMAL TRANSFER LENGTH if it is not a multiple of the device's

To make the sanity checking conditionals more readable--and to
facilitate printing warnings--relocate the checking to a helper
function. No functional change aside from the printks.

When the driver receives the tx completion of the
descriptor over ce, it clears the nbytes configured
for that particular descriptor. WCN3990 uses ce
descriptors with 64-bit address.
Currently during handling the tx completion of the
descriptors, the nbytes are accessed from the descriptors
using ce_desc for 32-bit targets. This will lead to clearing
of memory at incorrect offset if DMA MASK is set to greater
than 32 bits.

If the provided fwnode is an OF node, set dev.of_node as well.
Also add an of_node_reused flag to struct platform_device_info and copy
this to the new device. This is needed to avoid pinctrl settings being
requested twice. See 4e75e1d7dac9 ("driver core: add helper to reuse a
device-tree node") for a longer explanation.
Some drivers are just shims that create extra "glue" devices with the
DT device as parent and have the real driver bind to these. In these
cases, the glue device needs to get a reference to the original DT node
in order for the main driver to access properties and child nodes.
For example, the sunxi-musb driver creates such a glue device using
platform_device_register_full(). Consequently, devices attached to
this USB interface don't get associated with DT nodes, if present,
the way they do with EHCI.
This change will allow sunxi-musb and similar drivers to easily
propagate the DT node to child devices as required.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
Notice that, in this case, variable siz is not necessary, hence
it is removed.
This code was detected with the help of Coccinelle.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = alloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable size is not necessary, hence it is
removed.
This code was detected with the help of Coccinelle.

Current code does not really avoid array access out of bounds,
fix it by add checking for pdata->slew_rate.
If pdata->slew_rate is too big, it's a bug in pdata that needs fix.

Setup .vsel_reg and .vsel_mask then we can use the standard
set/get_voltage_sel_regmap helpers to simplify the code.

The wm831x_dcdc_ilim entries needs to be uA because it is used to compare
with min_uA and max_uA.
While at it also make the array const and change to use unsigned int.

This patch fixes two smatch warnings about two if statements that are
always true because of the types of the variables used - u32 when
comparing the sum to u32_max.
The patch changes the types to be u64 so the accumalted sum can be checked
if it is larger than u32_max
