Re: [PATCH 4/7] PCI/net: Use PCI_STD_NUM_BARS in loops instead of PCI_STD_RESOURCE_END

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The subject can be simply:

  <prefix>: Loop using PCI_STD_NUM_BARS

to keep them a little shorter so "git log --online" doesn't wrap.

  Refactor loops to use 'i < PCI_STD_NUM_BARS' instead of 'i <=
  PCI_STD_RESOURCE_END'.

This patch touches two unrelated drivers and should be split up.
When you do that, pay attention to the convention for commit log
prefixes, e.g.,

  $ git log --oneline drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c
