X-Git-Tag: v2.6.26-rc1~645
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=626adeb6675fdf60e9d8c6212776b0b0acf0e376;p=linux-2.6

Simplify initcall_debug output

print_fn_descriptor_symbol() prints the address if we don't have a symbol, so
no need to print both.

Also, combine printing return value with elapsed time.  Changes this:

  Calling initcall 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50()
  initcall 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50() returned 1.
  initcall 0xc05b7a70 ran for 0 msecs: pci_mmcfg_late_insert_resources+0x0/0x50()
  initcall at 0xc05b7a70: pci_mmcfg_late_insert_resources+0x0/0x50(): returned with error code 1

to this:

  calling  pci_mmcfg_late_insert_resources+0x0/0x50()
  initcall pci_mmcfg_late_insert_resources+0x0/0x50() returned 1 after 0 msecs
  initcall pci_mmcfg_late_insert_resources+0x0/0x50() returned with error code 1
