The 'hw' pointer local variable in this function became unused after
commit f5290d8e4f0c ("clk: asm9260: use parent index to link the
reference clock"). Remove it to silence an unused but set variable
warning.

Rewrite clk-asm9260 to use parent index to use the reference clock.
During this rework two helpers are added:
- clk_hw_register_mux_table_parent_data() to supplement
clk_hw_register_mux_table() but using parent_data instead of
parent_names
- clk_hw_register_fixed_rate_parent_accuracy() to be used instead of
directly calling __clk_hw_register_fixed_rate(). The later function is
an internal API, which is better not to be called directly.

The __clk_hw_register_fixed_rate_with_accuracy() function (with two '_')
does not exist, and apparently never did:
drivers/clk/clk-asm9260.c: In function 'asm9260_acc_init':
drivers/clk/clk-asm9260.c:279:7: error: implicit declaration of function '__clk_hw_register_fixed_rate_with_accuracy'; did you mean 'clk_hw_register_fixed_rate_with_accuracy'? [-Werror=implicit-function-declaration]
279 | hw = __clk_hw_register_fixed_rate_with_accuracy(NULL, NULL, pll_clk,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| clk_hw_register_fixed_rate_with_accuracy
drivers/clk/clk-asm9260.c:279:5: error: assignment to 'struct clk_hw *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
279 | hw = __clk_hw_register_fixed_rate_with_accuracy(NULL, NULL, pll_clk,
| ^
From what I can tell, __clk_hw_register_fixed_rate() is the correct
API here, so use that instead.

This fixed rate clk is registered with the accuracy of the parent. Use
CLK_FIXED_RATE_PARENT_ACCURACY for that instead of getting the parent
clk and finding out the accuracy that way.

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

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;
void *entry[];
};
instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);
This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
uses. It was done via automatic conversion with manual review for the
"CHECKME" non-standard cases noted below, using the following Coccinelle
script:
// pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
// sizeof *pkey_cache->table, GFP_KERNEL);
@@
identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc";
expression GFP;
identifier VAR, ELEMENT;
expression COUNT;
@@
- alloc(sizeof(*VAR) + COUNT * sizeof(*VAR->ELEMENT), GFP)
+ alloc(struct_size(VAR, ELEMENT, COUNT), GFP)
// mr = kzalloc(sizeof(*mr) + m * sizeof(mr->map[0]), GFP_KERNEL);

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

of_io_request_and map returns an error pointer, but the current code assumes
that on error the returned pointer will be NULL.
Obviously, that makes the check completely useless. Change the test to actually
check for the proper error code.
