slimbus: qcom: add missed clk_disable_unprepare in remove

slimbus: Use the correct style for SPDX License Identifier

2020-01-14T20:46:47+00:00

This patch corrects the SPDX License Identifier style in header file related to SLIMbus driver. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.

slimbus: qcom-ngd-ctrl: Use dma_request_chan() instead dma_request_slave_channel()

2020-01-14T20:46:47+00:00

dma_request_slave_channel() is a wrapper on top of dma_request_chan() eating up the error code. By using dma_request_chan() directly the driver can support deferred probing against DMA.

slimbus: fix slim_tid_txn()

2019-08-18T10:56:10+00:00

fix below issue reported by coccicheck ./drivers/slimbus/slimbus.h:440:3-46: duplicated argument to && or || Looks like this was a typo, SLIM_MSG_MC_REQUEST_CHANGE_VALUE is command which requires transaction ID, so fix it, this also fix the warning.

slimbus: qcom-ngd-ctrl: Add of_node_put() before return

2019-08-18T10:56:10+00:00

Each iteration of for_each_available_child_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. Hence add an of_node_put before the return in two places. Issue found with Coccinelle.

slimbus: core: generate uevent for non-dt only

2019-06-20T08:45:22+00:00

Rely on MODULE_ALIAS() for automatic kernel module loading, rather than basing it on the OF compatible. This ensures that drivers without of_device_id table, such as wcd9335, will be automatically loaded.

slimbus: remove redundant dev_err message

devm_ioremap_resource already contains error message, so remove the redundant dev_err message Signed-off-by: Ding Xiang Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: fix kerneldoc comments

2019-06-10T16:44:21+00:00

The kerneldoc comments in drivers/slimbus/stream.c were not properly formatted, leading to a distinctly unsatisfying "no structured comments found" warning in the docs build. Sprinkle some asterisks around so that the comments will be properly recognized. Signed-off-by: Jonathan Corbet Signed-off-by: Greg Kroah-Hartman

slimbus: fix a potential NULL pointer dereference in of_qcom_slim_ngd_register

2019-04-25T20:23:06+00:00

In case platform_device_alloc fails, the fix returns an error code to avoid the NULL pointer dereference. Signed-off-by: Kangjie Lu Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: core: add missing spin_lock_init on txn_lock
