Subject: mmc: core: export function mmc_do_release_host()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ab1efd271704416c9e6e9cb4e5f58e7e4c4260e6;p=linux-beck.git

mmc: core: export function mmc_do_release_host()

When using mmc_try_claim_host the corresponding release
function is mmc_do_release_host, which then also must
be exported.
