From c373643b8688836c1627a805875994fe0012fc17 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 25 May 2020 14:31:20 +0100 Subject: spi: Remove note about transfer limit for spi_write_then_read() Originally spi_write_then_read() used a fixed statically allocated buffer which limited the maximum message size it could handle. This restriction was removed a while ago so that we could dynamically allocate a buffer if required but the kerneldoc was not updated to reflect this, do so.
