USB: rename usb_buffer_alloc() and usb_buffer_free() users

2010-05-20T20:21:38+00:00

For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency. All call sites have been changed accordingly, except for staging drivers. Signed-off-by: Daniel Mack Cc: Alan Stern Cc: Pedro Ribeiro Signed-off-by: Greg Kroah-Hartman

USB misc: make USB device id constant

2010-03-02T22:54:17+00:00

The id_table field of the struct usb_device_id is constant in so it is worth to make the initialization data also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // Signed-off-by: Németh Márton Cc: Julia Lawall Cc: cocci@diku.dk Signed-off-by: Greg Kroah-Hartman

USB: usblcd, fix memory leak

2009-10-09T20:52:06+00:00

Stanse found a memory leak in lcd_probe. Instead of returning without releasing the memory, jump to the error label which frees it. http://stanse.fi.muni.cz/ Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds

USB: remove info() macro from usb/misc drivers

2008-10-17T21:41:09+00:00

USB should not be having it's own printk macros, so remove info() and use the system-wide standard of dev_info() wherever possible. Signed-off-by: Greg Kroah-Hartman

USB: remove warn() macro from usb drivers

2008-10-17T21:41:09+00:00

USB should not be having it's own printk macros, so remove warn() and use the system-wide standard of dev_warn() wherever possible. In the few places that will not work out, use a basic printk(). Signed-off-by: Greg Kroah-Hartman

USB: usblcd: Push down BKL into driver

2008-07-21T22:16:18+00:00

I'm pretty sure this can be eliminated however I couldn't prove (or find) what stopped the device vanishing mid IOCTL_GET_HARD_VERSION. Perhaps a USB wizard could double check that and see if the lock_kernel can go entirely. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman
