sunsu: Fix panic in case of nonexistent port at "console=ttySY" cmdline option

2013-03-28T19:17:07Z

[ Upstream commit cb29529ea0030e60ef1bbbf8399a43d397a51526 ] If a machine has X (X < 4) sunsu ports and cmdline option "console=ttySY" is passed, where X < Y <= 4, than the following panic happens: Unable to handle kernel NULL pointer dereference TPC: RPC: I7: Call Trace: [0000000000453a38] register_console+0x378/0x3e0 [0000000000576fa0] uart_add_one_port+0x2e0/0x340 [000000000057af40] su_probe+0x160/0x2e0 [00000000005b8a4c] platform_drv_probe+0xc/0x20 [00000000005b6c2c] driver_probe_device+0x12c/0x220 [00000000005b6da8] __driver_attach+0x88/0xa0 [00000000005b4df4] bus_for_each_dev+0x54/0xa0 [00000000005b5a54] bus_add_driver+0x154/0x260 [00000000005b7190] driver_register+0x50/0x180 [00000000006d250c] sunsu_init+0x18c/0x1e0 [00000000006c2668] do_one_initcall+0xe8/0x160 [00000000006c282c] kernel_init_freeable+0x12c/0x1e0 [0000000000603764] kernel_init+0x4/0x100 [0000000000405f64] ret_from_syscall+0x1c/0x2c [0000000000000000] (null) 1)Fix the panic; 2)Increment registered port number every successful probe.

serial: diminish usage of struct serial_uart_config

2012-09-05T20:15:07Z

This structure might have made sense many years ago, but at this point it is only used in one specific driver, and referenced in stale comments elsewhere. Rather than change the sunsu.c driver, simply move the struct to be within the exclusive domain of that driver, so it won't get inadvertently picked up and used by other serial drivers going forward. The comments referencing the now driver specific struct are updated accordingly. Note that 8250.c has a struct that is similar in usage, with the name serial8250_config; but is 100% independent and untouched here. Cc: "David S.

serial: sunsu.c - don't explicitly tie array size to dynamic entity

2012-09-05T20:15:07Z

The addition of 8250-like entities continues to grow, while this driver has a snapshot of a select few common 8250 UARTs. So it has no need to grow with the new additions, since it calls out its own (largely historic) static list which does not grow. Cc: "David S.

tty: sparc: rename drivers/tty/serial/suncore.h -> include/linux/sunserialcore.h

There are multiple users of this file from different source paths now, and rather than have ../ paths in include statements, just move the file to the linux header dir. Suggested-by: David S. Miller Signed-off-by: Paul Gortmaker Acked-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

treewide: Convert uses of struct resource to resource_size(ptr)

2011-06-10T12:55:36Z

Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers. Signed-off-by: Joe Perches Signed-off-by: Jiri Kosina

dt/serial: Eliminate users of of_platform_{,un}register_driver

2011-02-28T20:22:46Z

Get rid of users of of_platform_driver in drivers/serial. The of_platform_{,un}register_driver functions are going away, so the users need to be converted to using the platform_bus_type directly. Signed-off-by: Grant Likely Reviewed-by: Arnd Bergmann
