ASoC: soc-core: export function to find components
Drivers might need to use the ASoC core function to find out whether a particular component is already registered with ALSA core or not. Export the function so that drivers can use it outside of the file. Change-Id: I13e4a053de085974b0b53c392a9453e46f1aa66d Signed-off-by: Banajit Goswami <bgoswami@codeaurora.org>
