      This patch modifies the condition while freeing to match the condition
      used while allocation. This fixes the above warning which arises when
      array size is equal to PAGE_SIZE where allocation is done using kzalloc
      but free is done using vfree.

      ARM: OMAP2+: omap2plus_defconfig: EHCI driver is not stable, disable it · 06b4ba52
      Kevin Hilman 提交于
      The EHCI driver is not stable enough to be enabled by default.  In v3.5,
      it has at least the following problems:
      
      - warning dump during bootup
      - hang during suspend
      - prevents CORE powerdomain from entering retention during idle (even
        when no USB devices connected.)
      
      This demonstrates that this driver has not been thoroughly tested and
      therfore should not be enabled in the default defconfig.
      
      In addition, the problems above cause new PM regressions which need be
      addressed before this driver should be enabled in the default
      defconfig.
