Subject: [PATCH] rtw88: fix seq_file memory leak
Git-commit: eb9affaeff701ce90fcf476ff5332624f9d0ddd2
Patch-mainline: v5.4-rc1
References: git-fixes
When using single_open(), single_release() should be used instead
of seq_release(), otherwise there is a memory leak.
This is detected by Coccinelle semantic patch.
Fixes: e3037485c68e ("rtw88: new Realtek 802.11ac driver")
