Convert(and rename) vchiq_log_info() custom logging wrapping based on printk to use dynamic debug. The wrapper is now renamed to vchiq_log_debug() since most of the usage is around printing debug information. The log category is dictated by enum vchiq_log_category which will become the part of the debug string format that will be logged to dynamic debug (for grep). All the vchiq_log_info() calls are adjusted to use the modified wrapper vchiq_log_debug(). The existing custom logging for vchiq_log_info() also tries to log trace messages using SRVTRACE_LEVEL. This is simply moved to use the vchiq_log_debug() directly. Signed-off-by:

All the vchiq_log_warning() calls are adjusted to use the modified wrapper. While at that, remove the extraneous "----" from few of the warning string text. Signed-off-by:

Move vchiq_log_error() custom logging wrapper based on printk, to use dynamic debug. To categorise, enum vchiq_log_category has been introduced, which will become the part of the error string format that will be logged to dynamic debug (for grep). All the vchiq_log_error() calls are adjusted to use the dynamic debug wrapper. vchiq_loud_error_*() has been removed as a part of this patch and replaced with dev_err (so that they directly end up in kernel log, even if dynamic debug isn't enabled), which serves the purpose.

Pass struct device pointer to vchiq_init_slots(). In subsequent commits, vchiq_log_* macros will be ported to use dynamic debug (dev_dbg()), hence they need access to a struct device pointer. No functional changes intended in this commit. Signed-off-by:

Using strcpy has potential for buffer overflows. It should be replaced with strscpy where possible. In this case the return value of strcpy is not used, so we can safely replace it with strscpy. Signed-off-by:

vme_check_window() uses printk() for logging error message. This leads to the following checkpatch warning: WARNING: Prefer [subsystem eg: netdev]_err([subsystem]dev, ... then dev_err(dev, ... then pr_err(... to printk(KERN_ERR ... Use dev_err() instead. Pass VME bridge device to vme_check_window() so that the error message can be logged with the bridge device context. Signed-off-by:Soumya Negi <soumya.negi97@gmail.com> Suggested-by:

Don't log error message in find_bridge(). The printk() triggers a checkpatch warning: WARNING: Prefer [subsystem eg: netdev]_err([subsystem]dev, ... then dev_err(dev, ... then pr_err(... to printk(KERN_ERR ... It can't be replaced by dev_err() & using pr_err() is not helpful as it doesn't give much context to the user. It is better to remove it. Signed-off-by: -

Drops variable ret as it is unused in the code. This therefore modifies the return type of program_mode_registers() to void from int since the return value is being ignored in all function calls. This improves code readability and maintainability. Suggested-by:

Checkpatch suggests using strscpy() instead of strcpy(). The advantages of strscpy() are that it always adds a NUL terminator and prevents read/write overflows if the source string is not properly terminated. strcpy() lacks built-in bounds checking for the destination buffer, making it susceptible to buffer overflows. These overflows can lead to various unpredictable behaviors. In this specific context, both strscpy and strcpy performs the same operation without any functional difference. The reason for this equivalence is that the driver_name string "vme_fake" is shorter than the size of the fake_bridge->name array which is defined as 16 characters (struct vme_bridge {char name[VMENAMSIZ];...}). Thus, there is no risk of buffer overflow in either case. VMENAMSIZ variable holds a constant value of 16 (#define VMENAMSIZ 16) The null-terminated "vme_fake" string (static const char driver_name[] = "vme_fake";) can be safely copied into fake_bridge->name using either strscpy or strcpy. While using strscpy() does not address any bugs, it is considered a better practice and aligns with checkpatch recommendations. Reviewed-by:Dan Carpenter <dan.carpenter@linaro.org> Signed-off-by:

VC04 has now a independent bus vchiq_bus to register its devices. However, the module auto-loading for bcm2835-audio and bcm2835-camera currently happens through MODULE_ALIAS() macro specified explicitly. The correct way to auto-load a module, is when the alias is picked out from MODULE_DEVICE_TABLE(). In order to get there, we need to introduce vchiq_device_id and add relevant entries in file2alias.c infrastructure so that aliases can be generated. This patch targets adding vchiq_device_id and do_vchiq_entry, in order to generate those alias using the /script/mod/file2alias.c. Going forward the MODULE_ALIAS() from bcm2835-camera and bcm2835-audio will be dropped, in favour of MODULE_DEVICE_TABLE being used there. The alias format for vchiq_bus devices will be "vchiq:<dev_name>". Adjust the vchiq_bus_uevent() to reflect that. Signed-off-by:
