2018-06-20T19:01:33Z

[ Upstream commit b819439fea305a0bfd6ca23a7994fd1a8847c0d8 ] Fix two section mismatches in drivers.c: 1) Section mismatch in reference from the function alloc_tree_node() to the function .init.text:create_tree_node(). 2) Section mismatch in reference from the function walk_native_bus() to the function .init.text:alloc_pa_dev().

parisc: Fix out of array access in match_pci_device()

parisc: parisc_bus_type: use dev_groups and not dev_attrs for bus_type

2017-06-09T09:00:45Z

The dev_attrs field has long been "depreciated" and is finally being removed, so move the driver to use the "correct" dev_groups field instead for struct bus_type. Cc: "James E.J. Bottomley" Cc: Helge Deller Cc: Bart Van Assche Cc: Doug Ledford Cc: Signed-off-by: Greg Kroah-Hartman

treewide: Constify most dma_map_ops structures

Most dma_map_ops structures are never modified. Constify these structures such that these can be write-protected.

parisc: use KERN_CONT when printing device inventory

Recent changes to printk require KERN_CONT uses to continue logging messages. So add KERN_CONT to output of device inventory. Signed-off-by: Helge Deller

parisc: memory overflow, 'name' length is too short for using

2013-06-01T12:27:56Z

'path.bc[i]' can be asigned by PCI_SLOT() which can '> 10', so sizeof(6 * "%u:" + "%u" + '\0') may be 21. Since 'name' length is 20, it may be memory overflow. And 'path.bc[i]' is 'unsigned char' for printing, we can be sure the max length of 'name' must be less than 28. So simplify thinking, we can use 28 instead of 20 directly, and do not think of whether 'patchc.bc[i]' can '> 100'. Signed-off-by: Chen Gang Signed-off-by: Helge Deller
