This patch introduces the use of managed resource function
devm_clk_get instead of clk_get and removes corresponding call
to clk_put in the remove function.
To be compatible with the change various gotos are replaced with
direct returns, and unneeded label is dropped.

The code you've added is carefully checking the return pointer from
pvr2_hdw_get_ctrl_v4l() yet the original code did not operate this way.
The result is that now there's this "unbalanced" effect where it appears
that the validity of the pvr2_ctrl instance is only checked on one side

This patch optimize copy_to-from-in_user for arm 64bit architecture.
The copy template is using the memcpy.S as a base. This allows the
sharing of the copy template with all of the copy*.S files.

Commit 5d5cd85ff441 ("rsi: Fix failure to load firmware after memory
leak fix and fix the leak") also added a check on the allocation of
DMA-accessible memory that may directly return. In that case the
already allocated firmware data is leaked. Make sure the data is
always freed correctly. Detected

Ok. That makes me a bit less nervous. I was worried there was some

The Kconfig for this driver is currently:

...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
In build time vadduqm opcode is not being mapped
correctly.
Adding a new map in ppc-xlate to do this.

Do we really need to force the MIN_MEMORY_BLOCK_SIZE on small

What about this patch - which just uses max_pfn to choose
the block size.
