parenthesis
This patch fixes the format of the code. It properly formats lines that
should not end with a '(' as suggested by checkpath.pl.

Also use KBUILD_MODNAME for module name.
This driver is only used by RALINK MIPS MT7621 SoCs. Tested by building
against that target using OpenWrt with Linux 5.10.10.
Fixes the following error:
error: the following would cause module name conflict:
drivers/dma/mediatek/mtk-hsdma.ko
drivers/staging/mt7621-dma/mtk-hsdma.ko

If an error occurs after calling 'mtk_hsdma_init()', it must be undone by
a corresponding call to 'mtk_hsdma_uninit()' as already done in the
remove function.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>

expression ret;
struct platform_device *E;

ret =
(
platform_get_irq(E, ...)

platform_get_irq_byname(E, ...)

if ( \( ret < 0 \| ret <= 0 \) )
{

This is in preparation to allow it and the mt7621-dma drivers to be
built separately. They are completely independent pieces of software,
and the Kconfig specifies very different requirements.

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 = devm_kzalloc(dev, 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 = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.
