commit d887d6104a upstream.
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 ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }

-dev_err(...);

While we're here, remove braces on if statements that only have one
statement (manually).

Pass the size of a struct into kzalloc by pointer dereference. This
complies with the Linux kernel coding style and removes the possibility
for a bug if the pointer's type is changed.

Running clang-format on mtk-hsdma.c I noticed that few lines would not
need to be wrapped, since they fit 80 columns. This change changes such
lines to better fit the style-guide.

Function 'mtk_hsdma_start_transfer' uses 'tx_desc' pointer which can be
dereferenced before it is initializated. Initializate pointer before
avoiding the problem.
