      ARM: dts: imx6qdl-sabreauto: Fix storm of accelerometer interrupts · 7e5d0bf6

      The MMA8451 interrupt triggers as low level, so the GPIO6_IO31 pin
      needs to activate its pull up, otherwise it will stay always at low level
      generating multiple interrupts.
      
      The current device tree does not configure the IOMUX for this pin, so
      it uses whathever comes configured from the bootloader.
      
      The IOMUXC_SW_PAD_CTL_PAD_EIM_BCLK register value comes as 0x8000 from
      the bootloader, which has PKE bit cleared, hence disabling the
      pull-up.
      
      Instead of relying on a previous configuration from the bootloader,
      configure the GPIO6_IO31 pin with pull-up enabled in order to fix
      this problem.

      reset: Fix memory leak in reset_control_array_put() · 532f9cd6

      Memory allocated for 'struct reset_control_array' in

      reset_control_array_put() resulting in kmemleak showing
      the following backtrace.
