SubjectRe: [PATCH V2 2/2] EDAC: synopsys: re-enable the interrupts in intr_handler for V3.X Synopsys EDAC DDR

This also needs to be made human-readable: for example,
"zynqmp_get_error_info() reads the error information from the registers
when an interrupt for a {un-,}correctable error is raised."

Unknown word [wirtes] in commit message.

Please introduce a spellchecker into your patch creation workflow.

"which disables the error interrupts" - make it simple - no need for the
V3.X marketing bla.

I think you're catching my drift: our commit messages need to be
understandable and when read months, years from now, still to make
sense.

Why the forward declaration?

Why not simply move {enable,disable}_intr() upwards in that file?

Also, for both fixes: do you want them backported in stable kernels?

I think you do because they look like you'd want that v3.x support to
work with older kernels too.

If so, read the section about "Fixes:" in
Documentation/process/submitting-patches.rst

Thx.
