Subject: Subject: [PATCH] staging: media: meson: vdec: declare u32 as static
 const
Message-ID: <YHRWxeXA9m+Gt+e+@kali>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

Declared 32 bit unsigned int as static constant inside a function and
replaced u32[] {x,y} as canvas3, canvas4 in codec_h264.c
This indicates the value of canvas indexes will remain constant throughout execution.
