Description
In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8192e: Fix use after free in _rtl92e_pci_disconnect()
The free_rtllib() function frees the "dev" pointer so there is use
after free on the next line. Re-arrange things to avoid that.

• linux linux kernel (>= 3.2 < 4.4.294)
• linux linux kernel (>= 4.5 < 4.9.292)
