2024-05-30media: intel/ipu6: add csi2 port sanity check in notifier boundBingbu Cao
Invalid csi2 port will break the isys notifier bound ops as it is trying to access an invalid csi2 sub-device instance based on the port. It will trigger a mc warning, and it will cause the sensor driver to unbound an inexistent isys csi2 and crash. Adding a csi2 port sanity check, return error to avoid such case.

2024-05-22tracing/treewide: Remove second parameter of __assign_str()Steven Rostedt (Google)
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

This causes linkage failures with some configurations. Fix it by depending on COMMON_CLK.

2024-05-10media: bcm2835-unicam: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

The ipu6 driver allocated vmalloc memory for the firmware if request_firmware() somehow managed not to use vmalloc to allocate it. Still how the memory is allocated by request_firmware() is not specified in its API, so be prepared for kmalloc-allocated firmware, too. Instead of allocating new vmalloc-backed buffer for the firmware, obtain the pages from virtual addresses instead.
