[PATCH] staging/mt7621-dma: mtk-hsdma.c->hsdma-mt7621.c

[Ilya Lipnitskiy]

Also use KBUILD_MODNAME for module name.

This driver is only used by RALINK MIPS MT7621 SoCs. Tested by building
against that target using OpenWrt with Linux 5.10.10.

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

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.

regards,
dan carpenter

Apparently this was already merged?  Never mind then.  Once it's merged
it can't be changed.  No big stress...
