At http://www.mail-archive.com/linux-mmc@vger.kernel.org/msg08371.html (thread: "mmc: sdio: reset card during power_restore") we found and fixed a bug where mmc's runtime power management functions were not being called. We have now also made improvements to the SDIO powerup routine which could possibly mask this kind of issue in future. Add debug messages to the runtime PM hooks so that it is easy to verify if and when runtime PM is happening. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Chris Ball <cjb@laptop.org> |
