[ Upstream commit 8ba35b3a0046d6573c98f00461d9bd1b86250d35 ]
Clang warns:
samples/vfio-mdev/mtty.c:592:39: warning: implicit conversion from 'int'
to 'char' changes value from 162 to -94 [-Wconstant-conversion]
*buf = UART_MSR_DSR | UART_MSR_DDSR | UART_MSR_DCD;
~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~
1 warning generated.
Turns out that all uses of buf in this function ultimately end up stored
or cast to an unsigned type. Just use u8, which has the same number of
bits but can store this larger number so Clang no longer warns.
