Subject: + rtc-pm8xxx-fixup-checkpatch-style-issues.patch added to -mm tree To: joshc@xxxxxxxxxxxxxx,a.zummo@xxxxxxxxxxxx,sboyd@xxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Mon, 10 Mar 2014 13:48:01 -0700 The patch titled Subject: rtc: pm8xxx: fixup checkpatch/style issues has been added to the -mm tree. Its filename is rtc-pm8xxx-fixup-checkpatch-style-issues.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/rtc-pm8xxx-fixup-checkpatch-style-issues.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/rtc-pm8xxx-fixup-checkpatch-style-issues.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Josh Cartwright <joshc@xxxxxxxxxxxxxx> Subject: rtc: pm8xxx: fixup checkpatch/style issues This patchset is based on Stephen Boyd's PM8921 modernization/cleanups (http://lkml.kernel.org/g/1393441166-32692-1-git-send-email-sboyd@xxxxxxxxxxxxxx), and allows for this RTC driver to be usable again. This patch (of 6): Before performing additional cleanups to this driver, do the easy cleanups first.
