parport: Add support for the WCH382 2S/1P multi-IO card

2016-03-02T20:19:08+00:00

[ Upstream commit 2fdd8c8c5304901fa7dbb2ce5dbc90a1984cee3d ] WCH382 is a PCI-E card with 1 LPT and 2 DB9 COM ports detected as Serial controller: Device 1c00:3250 (rev 10) (prog-if 05 [16850]) Signed-off-by: Sergej Pupykin Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

parport: parport_pc: Implement architecture and device check to cut off false-positives

2014-09-24T06:14:28+00:00

We definitely know that only x86 (32-bit) architecture is affected by the issue, so implement a stub instead of the actual check for other architectures. We also know that motherboard LPT chipset is affected, so the port is either come from parport_pc_init (when `io' module param is used) or parport_pc_find_isa_ports (when default LPT ports are probbed: 0x378, 0x278, 0x3bc). In both cases the port considered as 'legacy' and `dev' member of struct parport is NULL. See also comments for `struct parport' in parport.h Signed-off-by: Matwey V. Kornilov Signed-off-by: Greg Kroah-Hartman

parport: parport_pc: Introduce intel_bug_present function.

2014-09-24T06:14:28+00:00

Put the code to check present of the Intel bug from parport_EPP_supported into new intel_bug_present function. The later also return ECR register to the state it has before function call. Signed-off-by: Matwey V. Kornilov Signed-off-by: Greg Kroah-Hartman

parport: fix menu breakage

2014-07-26T01:00:23+00:00

Do not split the PARPORT-related symbols with the new kconfig symbol ARCH_MIGHT_HAVE_PC_PARPORT. The split was causing incorrect display of these symbols -- they were not being displayed together as they should be. Fixes: d90c3eb31535 "Kconfig cleanup (PARPORT_PC dependencies)" Signed-off-by: Randy Dunlap Cc: Mark Salter Cc: Ingo Molnar Cc: stable@vger.kernel.org # for 3.13, 3.14, 3.15 Signed-off-by: Linus Torvalds

parport: convert use of typedef ctl_table to struct ctl_table

2014-06-06T23:08:15+00:00

This typedef is unnecessary and should just be removed. Signed-off-by: Joe Perches Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

parport: Add support for the WCH353 1S/1P multi-IO card

parport: fix interruptible_sleep_on race

2014-03-01T00:22:42+00:00

The interruptible_sleep_on function is can still lead to the deadlock mentioned in the comment above the caller, and we want to remove it soon, so replace it now with the race-free wait_event_interruptible.
