2011-08-22sound/soc/fsl/p1022_ds.c: add missing of_node_putJulia Lawall
dma_channel_np has been accessed at this point, so decrease its reference count before leaving the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; expression E1!=0,E2,E3,E4; statement S; iterator I; @@ ( if (...) { ... when != of_node_put(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...) S if (...) { ... when != x = E4 of_node_put(x); ... return ...; } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-06-09ASoC: p1022ds: fix incorrect referencing of device tree propertiesTimur Tabi
Device tree integer properties are encoded in big-endian format, but some of the Freescale ASoC drivers were assuming that the host is in big-endian format as well. Although this is true, it's better to use endian-safe accessors. Also add a check for a failed ioremap() call in the SSI driver.

2010-09-02ASoC: pl022_ds.c: Add of_node_put to avoid memory leakJulia Lawall
Add a call to of_node_put in the error handling code following a call to of_parse_phandle. This patch also moves the existing call to of_node_put tothe end of the error handling code, to make it possible to jump to of_node_put without doing the other cleanup operations. These appear to be disjoint operations, so the ordering doesn't matter. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression x; expression E,E1,E2; statement S; @@ *x = (of_find_node_by_path |of_find_node_by_name |of_find_node_by_phandle |of_get_parent |of_get_next_parent |of_get_next_child |of_find_compatible_node |of_match_node |of_find_node_by_type |of_find_node_with_property |of_find_matching_node |of_parse_phandle )(...); ... if (x == NULL) S <... when != x = E *if (...) { ... when != of_node_put(x) when != if (...) { ... of_node_put(x); ... } ( return <+...x...+>; | * return ...; ) } ...> ( E2 = x; | of_node_put(x); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Timur Tabi <timur@freescale.com> Acked-by: Liam Girdwood <lrg@slimlogic.uo.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2010-08-20ASoC: add support for the Freescale P1022 DS reference boardTimur Tabi
The Freescale P1022 is a dual-core e500-based SOC with multimedia capabilities, specifically the same SSI audio controller on the MPC8610. The P1022 DS reference board includes a P1022 and a Wolfson Microelectronics WM8776 codec.
