The 10bit column format from the HEVC codec is supported by the PISP BE, so add the configuration. It requires some additional handling as it packs 3 10bit samples into 32 bits, with 2 bits of padding. Alignment and calculating strides is therefore not quite as straightforward.

Will this type of statement be accepted upstream? It does the right thing with gcc, but is not standard C syntax.

Although there seems to be tons of this type of usage in other kernel source files.

Must be getting rusty - never seen that syntax before, had to look it up!

Technically it is not C code. It's a gcc extension (that clang also supports).
But the kernel allows many gcc extensions and this idiom is commonly used.
