[PATCH 00/32] treewide: fix some clang-analyze static analyzer warnings

[Ahmad Fatoum]

I ran scan-build while building barebox for sandbox with clang and
patched some of the reported issues.

Ahmad Fatoum (32):
  clk: define stub implementation for clk_get_parent
  clk: have SCMI and SiFive clock controllers depend on COMMON_CLK
  meminfo: support SANDBOX build with DEBUG log level
  net: phy: micrel: drop useless assignment of dummy read
  mci: core: drop useless assignment
  nvmem: core: propagate read failure
  fs: remove never-read initializer in mount_all()
  usb: otg: always propagate failure to register parameters
  usb: dwc2: gracefully handle unknown hs_phy_type
  state: propagate failure to fixup enum32 into DT
  of: silence warning about never-read error assignment
  commands: trigger: drop unused variable
  commands: tutorial: fix memory leak
  bthread: fix null pointer dereference in error path
  common: env: drop never-read initialization
  of: refactor for of_fixup_reserved_memory() for clarity
  password: avoid static analyzer false positive
  regmap-mmio: regmap_mmio_get_min_stride: unify branches for
    readability
  crypto: caam - delete unused variable
  misc: ubootvar: always initialize struct ubootvar_data::flag
  nvmem: core: drop always true condition
  of: fdt: gracefully handle out-of-place properties
  of: overlay: drop unused variable of_overlay_apply_dir()
  of: partition: drop unused variable
  serial: ns16550_pci: drop useless assignment
  phy: core: drop useless else clause
  fs: ext4: ext_barebox: handle ext_get_inode() errors
  fs: fat: propagate f_lseek failure
  fs: drop duplicate follow_managed() call
  lib: parse_area_spec: guard against NULL pointer dereference
  net: ping: propagate failure
  net: fastboot: keep error message initialized at all times
