crypto: cavium/nitrox - remove check of list iterator against head past the loop body

2022-04-08T08:26:43+00:00

When list_for_each_entry() completes the iteration over the whole list without breaking the loop, the iterator value will be a bogus pointer computed based on the head element. While it is safe to use the pointer to determine if it was computed based on the head element, either with list_entry_is_head() or &pos->member == head, using the iterator variable after the loop should be avoided. In preparation to limit the scope of a list iterator to the list traversal loop, use a dedicated pointer to point to the found element [1].

PCI: Change the type of probe argument in reset functions

2021-08-18T22:32:42+00:00

Change the type of probe argument in functions which implement reset methods from int to bool to make the context and intent clear.

PCI: Add pcie_reset_flr() with 'probe' argument

2021-08-17T20:23:13+00:00

Most reset methods are of the form "pci_*_reset(dev, probe)". pcie_flr() was an exception because it relied on a separate pcie_has_flr() function instead of taking a "probe" argument. Add "pcie_reset_flr(dev, probe)" to follow the convention. Remove pcie_has_flr(). Some pcie_flr() callers that did not use pcie_has_flr() remain. [bhelgaas: commit log, rework pcie_reset_flr() to use dev->devcap directly] Link: https://lore.kernel.org/r/20210817180500.1253-3-ameynarkhede03@gmail.com Signed-off-by: Amey Narkhede Signed-off-by: Bjorn Helgaas Reviewed-by: Raphael Norwitz

crypto: cavium/nitrox - Fix an error rhandling path in 'nitrox_probe()'

2021-06-11T07:08:06+00:00

If an error occurs after a successful 'ioremap()' call, it must be undone by a corresponding 'iounmap()' call, as already done in the remove function. Add a 'pf_sw_fail' label in the error handling path and add the missing 'iounmap()'. While at it, also add a 'flr_fail' label in the error handling path and use it to avoid some code duplication.
