2008-11-19gspca: Move the video device to a separate area.Jean-Francois Moine
From: Jean-Francois Moine <moinejf@free.fr> The video device was part of the gspca device. On device disconnection while streaming, the device structure is freed at close time. In this case, the remaining close job on the video device run out of allocated memory. Priority: high Signed-off-by: Jean-Francois Moine <moinejf@free.fr>
2008-11-18gspca: Lock the subdrivers via module_get/put.Jean-Francois Moine
From: Jean-Francois Moine <moinejf@free.fr> The previous subdriver protection against rmmod was done via the file operations table in the device descriptor. On device disconnection while streaming, the device structure was freed at close time, and the module_put still used the module name in the freed area. Now, explicit module get/put are done on open and close. Priority: high Signed-off-by: Jean-Francois Moine <moinejf@free.fr>

2008-11-13drivers/media: use ARRAY_SIZEMauro Carvalho Chehab
From: Julia Lawall <julia@diku.dk> ARRAY_SIZE is more concise to use when the size of an array is divided by the size of its type or the size of its first element. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @i@ @@ @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(E[...])) + ARRAY_SIZE(E) @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(T)) + ARRAY_SIZE(E) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
