tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21Z

Use this new function to make code more comprehensible, since we are reinitialzing the completion, not initializing.

drivers: misc: ti-st: fix potential race if st_kim_start fails

2013-08-30T19:08:04Z

If st_kim_start() fails registered protocols should be removed. This is done by calling st_reg_complete(), which as comment states is called with spin lock held. But in st_register() when st_kim_start fails it is called without holding spin lock, creating possibility of concurrent access to st_gdata data members. Hold spin lock while calling st_reg_complete if st_kim_start() fails. Signed-off-by: Oleksandr Kozaruk Signed-off-by: Greg Kroah-Hartman

misc: use platform_{get,set}_drvdata()

2013-05-30T12:46:15Z

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Signed-off-by: Jingoo Han Signed-off-by: Greg Kroah-Hartman

Revert "drivers/misc/ti-st: remove gpio handling"

2013-01-23T01:22:47Z

This reverts commit eccf2979b2c034b516e01b8a104c3739f7ef07d1. The reason is that it broke TI WiLink shared transport on Panda. Also, callback functions should not be added to board files anymore, so revert to implementing the power functions in the driver itself. Additionally, changed a variable name ('status' to 'err') so that this revert compiles properly.

tty: Added a CONFIG_TTY option to allow removal of TTY

2013-01-19T00:15:27Z

The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY. The list is filtered to not show removed entries with awk '$3 != "-"' as the list was very long. add/remove: 0/226 grow/shrink: 2/14 up/down: 6/-35356 (-35350) function old new delta chr_dev_init 166 170 +4 allow_signal 80 82 +2 static.__warned 143 142 -1 disallow_signal 63 62 -1 __set_special_pids 95 94 -1 unregister_console 126 121 -5 start_kernel 546 541 -5 register_console 593 588 -5 copy_from_user 45 40 -5 sys_setsid 128 120 -8 sys_vhangup 32 19 -13 do_exit 1543 1526 -17 bitmap_zero 60 40 -20 arch_local_irq_save 137 117 -20 release_task 674 652 -22 static.spin_unlock_irqrestore 308 260 -48 Signed-off-by: Joe Millenbach Reviewed-by: Jamey Sharp Reviewed-by: Josh Triplett Signed-off-by: Greg Kroah-Hartman

misc: st_core: Error triggered by convert "char" to "int"

2013-01-17T18:19:42Z

When st driver decodes protocol index received from raw data, it does a value convert from "char" to "int". Because it's sign extension from bit8 to bit32, the "int" value maybe minus, in another word, the protocol index might be minus, but driver doesn't filter such case and may continue access memory pointed by this minus index. This patch is to change the variable type of index from "int" to "unsigned char", so that it avoids do such kind of type conversion. cc: liu chuansheng Signed-off-by: channing Signed-off-by: Greg Kroah-Hartman
