drivers: soc: qcom: rpmh-rsc: Correct check for slot number

2019-04-10T04:40:09+00:00

The return index value from bitmap_find_next_zero_area can be higher
than available slot. So correct the check to return error in such case.

soc: qcom: cmd-db: Fix an error code in cmd_db_dev_probe()

2019-03-28T04:32:26+00:00

The memremap() function doesn't return error pointers, it returns NULL.
This code is returning "ret = PTR_ERR(NULL);" which is success, but it
should return -ENOMEM.

soc: qcom: qmi: Change txn wait to non-interruptible

2019-03-28T04:32:26+00:00

Current QMI clients are not userspace facing, if their threads are
signaled, they do not do any signal checking or propagate the
ERESTARTSYS return code up. Remove the interruptible option so clients
can finish their QMI transactions even if the thread is signaled.

soc: qcom: rmtfs: Add support for mmap functionality

2019-03-28T04:32:25+00:00

This change adds mmap functionality to rmtfs_mem driver.
Userspace application can map the address and use this
mapped address directly as buffer for read/write call to disk.
and avoid the read/write call to the shared path to copy the
buffer to userspace application.

qcom: soc: llcc-slice: Clear the global drv_data pointer on error

2019-02-12T21:27:14+00:00

Currently the data structure for llc-slice is devm allocated and
stored as a global but never cleared if the probe function fails.
This is a problem because devm managed memory gets freed on probe
failure the API functions could access the pointer after it has been
freed.

Initialize the drv_data pointer to an error and reset it to an error
on probe failure or device destroy and add protection to the API
functions to make sure the memory doesn't get accessed.
