Subject: [media] rc-core.h: Surround macro with do {} while (0)
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=86b0dbef777a1fbb9922e304f047921d4e9d9c40;p=deliverable%2Flinux.git

[media] rc-core.h: Surround macro with do {} while (0)

Macros coded with if statements should be do { if... } while (0)
so the macros can be used in other if tests.

Use ##__VA_ARGS__ for variadic macro as well.
