Compilation error against kernel 6.8.x

[pavelrangelov]

Can't compile anymore with kernel 6.8.x. With kernel 6.5.0 it compiles without errors. Distro: Kubuntu 22.04.4 LTS

rtl8188eus/os_dep/linux/usb_intf.c:310:17: error: ‘struct usb_driver’ has no member named ‘drvwrap’ .usbdrv.drvwrap.driver.shutdown = rtw_dev_shutdown,

rtl8188eus/os_dep/linux/usb_intf.c:310:43: error: initialization of ‘const char *’ from incompatible pointer type ‘void (*)(struct device *)’ [-Werror=incompatible-pointer-types]

I found a similar driver that has already been patched for the 6.8.x kernel. So I applied the changes to this driver and it compiles and works. Except for a bunch of warnings about missing function prototypes (probably missing some header file). This is my temporary solution until the driver is fixed.
