Merge tag 'h8300-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull h8300 platform removal from Guenter Roeck:
"The patch series has been in -next for more than one relase cycle. I
did get a number of Acks, and no objections.
H8/300 has been dead for several years, the kernel for it has not
compiled for ages, and recent versions of gcc for it are broken.
Remove support for it"
