Suspending the IPA hardware is now managed by the runtime PM core code. The ->runtime_idle callback returns a non-zero value, so it will never suspend except when forced. As a result, there's no need to take an extra "do not suspend" clock reference. Signed-off-by: Alex Elder <redacted> --- drivers/net/ipa/ipa_main.c | 11 ----------- 1 file changed, 11 deletions(-)
