This is a note to let you know that I have just added a patch titled regulator: max8998: Ensure enough delay time for to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From d9a408d96739d4f314d92035908c9c534a709f23 Mon Sep 17 00:00:00 2001 From: Axel Lin <axel.lin@ingics.com> Date: Wed, 9 Jan 2013 19:34:57 +0800 Subject: [PATCH] regulator: max8998: Ensure enough delay time for max8998_set_voltage_buck_time_sel commit 81d0a6ae7befb24c06f4aa4856af7f8d1f612171 upstream. Use DIV_ROUND_UP to prevent truncation by integer division issue. This ensures we return enough delay time.
