Description

In the Linux kernel, the following vulnerability has been resolved: media: [next] staging: media: atomisp: fix memory leak of object flash In the case where the call to lm3554_platform_data_func returns an error there is a memory leak on the error return path of object flash. Fix this by adding an error return path that will free flash and rename labels fail2 to fail3 and fail1 to fail2.
