2010-10-24can: at91_can: fix reception of extended framesMarc Kleine-Budde
The AT91_MID_MIDE bit must be set in order to receive extended frames. The reception of an extended frame sets this bit, while reception of standard frames resets it. This results in some lost extended frames in an extended ID only environment. But leads to unpredictable lost extended ID frames in a mixed environment. The problem is fixed by setting the AT91_MID_MIDE after reception of a CAN frame. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-10-18can: mcp251x: Don't use pdata->model for chip selection anymoreMarc Kleine-Budde
Since commit e446630c960946b5c1762e4eadb618becef599e7, i.e. v2.6.35-rc1, the mcp251x chip model can be selected via the modalias member in the struct spi_board_info. The driver stores the actual model in the struct mcp251x_platform_data. From the driver point of view the platform_data should be read only. Since all in-tree users of the mcp251x have already been converted to the modalias method, this patch moves the "model" member from the struct mcp251x_platform_data to the driver's private data structure.

2010-09-01drivers/net/can/mscan/mpc5xxx_can.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_find_matching_node. This patch also moves the existing call to of_node_put after the call to iounmap in the error handling code, to make it possible to jump to of_node_put without doing iounmap. These appear to be disjoint operations, so the ordering doesn't matter. This patch furthermore changes the -ENODEV result in the error handling code for of_find_matching_node to a return of 0, as found in the error handling code for of_iomap, because the return type of the function is unsigned. 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> Reviewed-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S.

2010-05-18can: Fix SJA1000 command register writes on SMP systemsOliver Hartkopp
The SJA1000 command register is concurrently written in the rx-path to free the receive buffer _and_ in the tx-path to start the transmission. The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states: "Between two commands at least one internal clock cycle is needed in order to proceed. The internal clock is half of the external oscillator frequency." On SMP systems the current implementation leads to a write stall in the tx-path, which can be solved by adding some general locking and some time to settle the write_reg() operation for the command register. Thanks to Klaus Hitschler for the original fix and detailed problem description. This patch applies on net-2.6 and (with some offsets) on net-next-2.6 .
