Subject: tracing: Introduce TRACE_FIELD_ZERO() macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d93f12f3f417e49a175800da85c6fcb2a5096e03;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tracing: Introduce TRACE_FIELD_ZERO() macro

Use TRACE_FIELD_ZERO(type, item) instead of TRACE_FIELD_ZERO_CHAR(item).
This also includes a typo fix of TRACE_ZERO_CHAR() macro.
