The only part of this commit message that I could understand at all was
the parts which were copy and pasted from the build system...  :/
Please, write it like this:

[PATCH] staging/mt7621-dma: fix build conflict

This driver cannot be built because we have two modules with the same
name and it leads to an error:

  error: the following would cause module name conflict:
    drivers/dma/mediatek/mtk-hsdma.ko
    drivers/staging/mt7621-dma/mtk-hsdma.ko

The fix is to rename mtk-hsdma.c to hsdma-mt7621.c.  Also we can use the
KBUILD_MODNAME where appropriate instead of hard coding the name.
