[PATCH 01/10] libcamera: base: log: Declare log categories when defining them

[Laurent Pinchart]

libcamera will enable -Wmissing-declarations to catch mismatches between
function declarations and definitions. There is one offender in log.h:
when a category is defined with LOG_DEFINE_CATEGORY(), it generates a
function with no declaration. Fix it by declaring the function using
LOG_DECLARE_CATEGORY() as the first step fo the category definition.
