[PATCH 00/14] Smatch warning fixups

[Lucas Stach]

I've run smatch over a imx_v7_defconfig build
and fixed the resulting warnings.

Some of them are just minor issues with no
real impact, but some of them are real potential
problems or even real bugs.

Lucas Stach (14):
  remove redundant NULL check on free
  commands: edit: properly propagate error code
  common: env: properly propagate error code
  clk: imx: unsigned mfn is never less than zero
  lib: math: fix return path (numstack may be NULL)
  lib: libbb: f should never be NULL
  comamnds: uimage: actually print error message
  usb: ulpi: fix logic-op
  usb: dfu: fix error path to avoid NULL ptr deref
  net: usb: smsc95xx: fix wrong phy reset condition
  net: usb: asix: properly propagate error code
  mtd: core: avoid possible NULL ptr deref
  clk: avoid possible NULL ptr deref
  don't cast negative error codes to unsigned size_t
