Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
staging: rtl8723bs: fix potential memory leak in rtw_init_drv_sw()<br />
<br />
In rtw_init_drv_sw(), there are various init functions are called to<br />
populate the padapter structure and some checks for their return value.<br />
However, except for the first one error path, the other five error paths<br />
do not properly release the previous allocated resources, which leads to<br />
various memory leaks.<br />
<br />
This patch fixes them and keeps the success and error separate.<br />
Note that these changes keep the form of `rtw_init_drv_sw()` in<br />
"drivers/staging/r8188eu/os_dep/os_intfs.c". As there is no proper device<br />
to test with, no runtime testing was performed.
