2013-01-25drivers, vmci: Fix build errorDavid Rientjes
We can't rely on vmalloc.h being included by other included files because under some configs it is possible for the build to fail: drivers/misc/vmw_vmci/vmci_queue_pair.c: In function 'qp_free_queue': drivers/misc/vmw_vmci/vmci_queue_pair.c:270: error: implicit declaration of function 'vunmap' drivers/misc/vmw_vmci/vmci_queue_pair.c:277: error: implicit declaration of function 'vfree' drivers/misc/vmw_vmci/vmci_queue_pair.c: In function 'qp_alloc_queue': drivers/misc/vmw_vmci/vmci_queue_pair.c:302: error: implicit declaration of function 'vmalloc' drivers/misc/vmw_vmci/vmci_queue_pair.c:302: warning: assignment makes pointer from integer without a cast drivers/misc/vmw_vmci/vmci_queue_pair.c:324: error: implicit declaration of function 'vmap' drivers/misc/vmw_vmci/vmci_queue_pair.c:324: error: 'VM_MAP' undeclared (first use in this function) drivers/misc/vmw_vmci/vmci_queue_pair.c:324: error: (Each undeclared identifier is reported only once drivers/misc/vmw_vmci/vmci_queue_pair.c:324: error: for each function it appears in.) drivers/misc/vmw_vmci/vmci_queue_pair.c: In function 'qp_host_map_queues': drivers/misc/vmw_vmci/vmci_queue_pair.c:843: error: 'VM_MAP' undeclared (first use in this function) Fix the build by directly including vmalloc.h.

2013-01-22VMCI: Fix broken context ID retrievalAndy King
I'm an idiot. The context ID can be a really large unsigned number, which means it'll appear negative as an int. So actually the right fix here is just to set it regardless of the returned value (but only for this particular hypercall; normally we would check it).

2013-01-21Revert "drivers/misc/ti-st: remove gpio handling"Luciano Coelho
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.

2013-01-17misc: st_core: Error triggered by convert "char" to "int"channing
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 <chuansheng.liu@intel.com> Signed-off-by: channing <chao.bi@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
