The macro UVC_INFO_QUIRK(q) in uvc_driver.c initializes a structure
using a compound literal, and the complex value within the macro was
not properly enclosed in parentheses. This could lead to operator
precedence issues and reduced code clarity.

This commit adds an extra set of parentheses to the macro definition
to ensure correct evaluation and adherence to best practices. This
change also improves code readability and portability.
