[PATCH] PCI: probe: Fix spacing around operators
Posted by hechushiguitu666@gmail.com 1 month, 1 week ago
From: "haoyu.lu" <hechushiguitu666@gmail.com>

Fix checkpatch.pl warnings for missing spaces around operators:

- size-1 -> size - 1

- PCI_BRIDGE_RESOURCES+i -> PCI_BRIDGE_RESOURCES + i

- 60*1000 -> 60 * 1000

Convert to pci_resource_n().

This should use linux/units.h *_PER_* constant instead of 1000.

[PATCH v2] PCI: probe: Use helper macros and constants
Posted by hechushiguitu666@gmail.com 1 month, 1 week ago
From: "haoyu.lu" <hechushiguitu666@gmail.com>

Replace direct resource array access with the pci_resource_n() helper
macro and use MSEC_PER_SEC instead of the bare number 1000.

Changes in v2:
- Use pci_resource_n() for resource array access (Bjorn)
- Use MSEC_PER_SEC (Bjorn)
