Using kfree() to\nrelease this vmalloc-backed buffer can lead to memory corruption.\n\nUse rtw_hal_data_deinit() to pair the free correctly and free\nHalData with vfree().\n\nThe bug was first flagged by an experimental static analysis tool we\nare developing for kernel memory-management bugs. Manual inspection\nconfirms that the issue is still present in current mainline.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\nsuitable RTL8723BS SDIO hardware to test with, no runtime testing was\nable to be performed."
