net/rfkill/rfkill-gpio.c: introduce missing kfree

2012-01-04T19:30:46Z

Error handling code following a kmalloc should free the allocated data. The label fail_alloc already does this for rfkill. A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } x->f1 ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // Signed-off-by: Julia Lawall Signed-off-by: John W.

net: rfkill: convert net/rfkill/* to use module_platform_driver()

2011-11-30T20:08:27Z

This patch converts the drivers in net/rfkill/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler. Cc: "David S. Miller" Cc: "John W.

net:rfkill: add a gpio setup function into GPIO rfkill

2011-10-03T19:19:19Z

Add a gpio setup function which gives a chance to set up platform specific configuration such as pin multiplexing, input/output direction at the runtime or booting time. Signed-off-by: Sangwook Lee Signed-off-by: John W. Linville

net: rfkill: add generic gpio rfkill driver

2011-05-19T17:53:54Z

This adds a new generic gpio rfkill driver to support rfkill switches which are controlled by gpios. The driver also supports passing in data about the clock for the radio, so that when rfkill is blocking, it can disable the clock. This driver assumes platform data is passed from the board files to configure it for specific devices. Original-patch-by: Anantha Idapalapati Signed-off-by: Rhyland Klein Signed-off-by: John W.
