The patch titled Subject: rtc: omap: silence bogus power-up reset message at probe has been removed from the -mm tree. Its filename was rtc-omap-silence-bogus-power-up-reset-message-at-probe.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Johan Hovold <johan@xxxxxxxxxx> Subject: rtc: omap: silence bogus power-up reset message at probe Some legacy RTC IP revisions has a power-up reset flag in the status register that later revisions lack. As this flag is always read back as set on later revisions (or is overloaded with a different flag), make sure to only clear the flag and print the info message on legacy platforms.
