atm: zatm: Fix empty body Clang warnings

2018-10-18T22:39:10+00:00

Clang warns:

drivers/atm/zatm.c:513:7: error: while loop has empty body
[-Werror,-Wempty-body]
        zwait;
             ^
drivers/atm/zatm.c:513:7: note: put the semicolon on a separate line to
silence this warning

Get rid of this warning by using an empty do-while loop. While we're at
it, add parentheses to make it clear that this is a function-like macro.

atm: eni: Move semicolon to a new line after empty for loop

2018-10-18T22:38:26+00:00

Clang warns:

drivers/atm/eni.c:244:48: error: for loop has empty body
[-Werror,-Wempty-body]
        for (order = 0; (1 << order) < *size; order++);
                                                      ^
drivers/atm/eni.c:244:48: note: put the semicolon on a separate line to
silence this warning

In this case, that loop is expected to be empty so silence the warning
in the way that Clang suggests.

fore200e: check for dma mapping failures

2018-10-11T05:38:50+00:00

The driver was lacking any handling for failures from the DMA mapping
routines.  With an iommu or swiotlb this can be fatal.

fore200e: don't use GFP_DMA

2018-10-11T05:38:50+00:00

The driver properly uses the DMA mapping API, so it should not
pointlessly dip into the GFP_DMA pool, which is only 16MB on x86.

fore200e: devirtualize dma alloc calls

2018-10-11T05:38:50+00:00

There is no need for an indirection before calling the dma alloc
routines now that we store a struct device in struct fore200e.

Also remove the pointless GFP_ATOMIC for the sbus case, and fix the
up the error handling by removing the 0 dma_addr test - some iommus
can return 0 as a perfectly valid bus address.

fore200e: remove the align_size field of struct chunk

2018-10-11T05:38:50+00:00

There is no need for this field, as the only user of it can just use
the local size variable instead.
