Subject: rpmsg: core: Make remove handler for rpmsg driver optional.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=54119bc1110dab2fa389f45c73a0787b8e037e8b;p=linux.git

rpmsg: core: Make remove handler for rpmsg driver optional.

Most other bus (for example, SPI, i2c) have the remove handler for
driver optional. Make remove handler for rpmsg driver optional too.
