Hi,
This series of patches removes unnecessary explicit u8 and u16 type
casts. They are broken down into 7 patches as follows:
Patch 1 removes u8 casts in assignment statements of u8 variables.
Patch 2 removes u8 casts in u8 arguments to function calls.
Patch 3 removes u8 casts in comparison expressions.
Patch 4 removes u16 casts in assignment statements.
Patch 5 removes the u16 cast in the u16 argument to a function call.
Patch 6 removes the u16 cast because the function parameter is u32.
Patch 7 removes the u16 cast from a function return statement.
Justification is found in the respective changelogs.
Cheers,
Solomon
Since the macro VERSION_8190_BD is defined to be 0x3, and the structure
members card_8192_version and IC_Cut are both u8, an explicit u8 cast is
unnecessary.

Remove the explicit casts in assignment statements for u16 variables.
Because these variables are declared as u16, there is implicit
conversion to u16 during the assignment, so an explicit cast is
unnecessary.

2.36.0
Remove the unnecessary explicit u8 casts for u8 arguments in function
calls. These functions have declared their parameters to be of type u8,
so the arguments given to those parameters will be automatically coerced
to u8. Therefore, an explicit cast is unnecessary.

The explicit u16 cast is not necessary because rtl92e_eeprom_read's
second parameter is defined to be u32.

Remove the explicit u16 casts for u16 argument in the function call. This
function has declared its parameter to be of type u16, so the argument
given to that parameter will be automatically coerced to u16. Therefore,
an explicit cast is unnecessary.

Remove explicit u16 cast of the function Mk16 return value.
The variable hi does not need to be casted explicitly to u16 as it will
already be casted implicitly.
