Merge misc patches from Andrew Morton: - Florian has vanished so I appear to have become fbdev maintainer again :( - Joel and Mark are distracted to welcome to the new OCFS2 maintainer - The backlight queue - Small core kernel changes - lib/ updates - The rtc queue - Various random bits * akpm: (164 commits) rtc: rtc-davinci: use devm_*() functions rtc: rtc-max8997: use devm_request_threaded_irq() rtc: rtc-max8907: use devm_request_threaded_irq() rtc: rtc-da9052: use devm_request_threaded_irq() rtc: rtc-wm831x: use devm_request_threaded_irq() rtc: rtc-tps80031: use devm_request_threaded_irq() rtc: rtc-lp8788: use devm_request_threaded_irq() rtc: rtc-coh901331: use devm_clk_get() rtc: rtc-vt8500: use devm_*() functions rtc: rtc-tps6586x: use devm_request_threaded_irq() rtc: rtc-imxdi: use devm_clk_get() rtc: rtc-cmos: use dev_warn()/dev_dbg() instead of printk()/pr_debug() rtc: rtc-pcf8583: use dev_warn() instead of printk() rtc: rtc-sun4v: use pr_warn() instead of printk() rtc: rtc-vr41xx: use dev_info() instead of printk() rtc: rtc-rs5c313: use pr_err() instead of printk() rtc: rtc-at91rm9200: use dev_dbg()/dev_err() instead of printk()/pr_debug() rtc: rtc-rs5c372: use dev_dbg()/dev_warn() instead of printk()/pr_debug() rtc: rtc-ds2404: use dev_err() instead of printk() rtc: rtc-efi: use dev_err()/dev_warn()/pr_err() instead of printk() ...
