Subject: [PATCH v4 0/3] Fix find_first_zero_bit() usage
Date: Tue, 12 Dec 2017 15:16:31 +0100	[thread overview]
Message-ID: <20171212141634.5985-1-niklas.cassel@axis.com> (raw)

find_first_zero_bit()'s parameter 'size' is defined in bits,
not in bytes.

Calling find_first_zero_bit() with the wrong size unit
will lead to insidious bugs.

Fix all uses of find_first_zero_bit() called with
sizeof() as size argument in drivers/pci.

Also had to fix broken error handling in pci_epc_epf_link()
in order to do proper error handling for find_first_zero_bit().

  PCI: endpoint: Fix error handling in pci_epc_epf_link()
