i3c master: fix missing destroy_workqueue() on error in i3c_master_register

2021-01-06T13:48:40+00:00

[ Upstream commit 59165d16c699182b86b5c65181013f1fd88feb62 ] Add the missing destroy_workqueue() before return from i3c_master_register in the error handling case.

i3c: master add i3c_master_attach_boardinfo to preserve boardinfo

2020-10-29T08:57:45+00:00

[ Upstream commit 9da36a7ec42135428e1d41621e3703429bda3b2e ] Boardinfo was lost if I3C object for devices with boardinfo available are not created or not added to the I3C device list because of some failure e.g. SETDASA failed, retrieve info failed etc This patch adds i3c_master_attach_boardinfo which scan boardinfo list in the master object and 'attach' it to the I3C device object.

i3c: master: Use dev_to_i3cmaster()

2019-08-27T07:43:59+00:00

Since we have dev_to_i3cmaster() available, use it. Signed-off-by: Axel Lin Signed-off-by: Boris Brezillon

i3c: master: fix a memory leak bug

2019-08-12T08:11:29+00:00

In i3c_master_getmwl_locked(), the buffer used for the dest payload data is allocated using kzalloc() in i3c_ccc_cmd_dest_init(). Later on, the length of the dest payload data is checked against 'sizeof(*mwl)'. If they are not equal, -EIO is returned to indicate the error. However, the allocated buffer is not deallocated on this path, leading to a memory leak. To fix the above issue, free the buffer before returning the error.

i3c: add addr and lvr to i2c_dev_desc structure

2019-08-11T08:48:28+00:00

I need to store address and lvr value for I2C devices without static definition in DT. This allows secondary master to transmit DEFSLVS command properly. Main changes between v4 and v5: - Change in defslvs to use addr and lvr from i2c_dev_desc structure - Change in CDNS and DW drivers to use addr and lvr from i2c_dev_desc structure Signed-off-by: Przemyslaw Gaj Signed-off-by: Boris Brezillon

i3c: master: cdns: Use for_each_set_bit()

2019-08-11T08:45:52+00:00

This simplifies and standardizes slot manipulation code by using for_each_set_bit() library function. Signed-off-by: Andy Shevchenko Signed-off-by: Boris Brezillon

i3c: master: Add of_node_put() before return

2019-08-11T08:45:51+00:00

Each iteration of for_each_available_childe_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Add an of_node_put before the return. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta Signed-off-by: Boris Brezillon

i3c: move i3c_device_match_id to device.c and export it

2019-07-27T09:22:19+00:00

Some I3C device drivers need to know which entry matches the i3c_device object passed to the probe function Let's move i3c_device_match_id() to device.c and export it so it can be used by drivers. Signed-off-by: Vitor Soares Signed-off-by: Boris Brezillon
