Date: Mon, 25 Jan 2016 16:48:28 +0100 From: Arnd Bergmann <arnd@...db.de> To: "Rafael J. Wysocki" <rjw@...ysocki.net>, Pavel Machek <pavel@....cz>, Len Brown <len.brown@...el.com> Cc: linux-arm-kernel@...ts.infradead.org, Jiri Kosina <jikos@...nel.org>, Arnd Bergmann <arnd@...db.de>, linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] power: APM_EMULATION does not depend on PM The APM emulation code does multiple things, and some of them depend on PM_SLEEP, while the battery management does not. However, selecting the symbol like SHARPSL_PM does causes a Kconfig warning: warning: (SHARPSL_PM && PMAC_APM_EMU) selects APM_EMULATION which has unmet direct dependencies (PM && SYS_SUPPORTS_APM_EMULATION) >From all I can tell, this is completely harmless, and we can simply allow APM_EMULATION to be enabled here, even if PM is not.
