Subject: Un-inline get_pipe_info() helper function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=72083646528d4887b920deb71b37e09bc7d227bb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Un-inline get_pipe_info() helper function

This avoids some include-file hell, and the function isn't really
important enough to be inlined anyway.
