Subject: bw2: use standard fields for framebuffer physical address and length
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3f06cd29358dd390d62afcde14fde54cec9deef9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

bw2: use standard fields for framebuffer physical address and length

Use standard fields fbinfo.fix.smem_start and fbinfo.fix.smem_len
for physical address and length of framebuffer.

This also fixes output of the 'fbset -i' command - address and length
of the framebuffer is displayed correctly.
