[Linux-kernel-mentees] [PATCH v2] staging: rtl8192e: fix bool comparison in expressions

[Aditya Srivastava]

There are certain conditional expressions in rtl8192e, where a boolean
variable is compared with true/false, in forms such as (foo == true) or
(false != bar), which does not comply with checkpatch.pl (CHECK:
BOOL_COMPARISON), according to which boolean variables should be
themselves used in the condition, rather than comparing with true/false

E.g. in drivers/staging/rtl8192e/rtl8192e/r8192E_dev.c,
"if (Type == true)" can be replaced with: "if (Type)"

Replace all such expressions with the bool variables appropriately

- the changes made are compile tested
- the patch applies perfectly over next-20201218

Changes in v2:
- drivers/staging/rtl8192e/rtl8192e/r8192E_dev.c: Replace "else if (!Type)" with "else"
- drivers/staging/rtl8192e/rtllib_rx.c: Remove bracket from "(!ieee->pHTInfo->bCurRxReorderEnable)"
- drivers/staging/rtl8192e/rtllib_rx.c: Put bToOtherSTA on previous line
