staging: rtl8723bs: fix copy of overlapping memory
commit8ae9a588ca
upstream. Currently the rtw_sprintf prints the contents of thread_name onto thread_name and this can lead to a potential copy of a string over itself. Avoid this by printing the literal string RTWHALXT instread of the contents of thread_name. Addresses-Coverity: ("copy of overlapping memory") Fixes:554c0a3abf
