Hi Frank, Thanks for the patch. On Thu, Oct 29, 2026 at 12:30:37PM -0400, Frank.Li@oss.nxp.com wrote:
From: Frank Li <Frank.Li@nxp.com> When CONFIG_PM is not enabled, all devices runtime PM state should be treated as active. __pm_runtime_resume() returns 1 (called by pm_runtime_get()). pm_runtime_get_if_active() is the try-and-get version of pm_runtime_get(). stub pm_runtime_active() also returns true. So pm_runtime_get_if_active() should return the same value as the stub pm_runtime_get(), which is 1.
Shouldn't the same change be done to pm_runtime_get_if_in_use()? It's
otherwise the same, except that it requires also the use count to be
non-zero.
