From 1f5e7518f063728aee0679c5086b92d8ea429e11 Mon Sep 17 00:00:00 2001 From: Luiz Sampaio Date: Wed, 19 May 2021 19:30:44 -0300 Subject: w1: ds2438: fixing bug that would always get page0 The purpose of the w1_ds2438_get_page function is to get the register values at the page passed as the pageno parameter. However, the page0 was hardcoded, such that the function always returned the page0 contents. Fixed so that the function can retrieve any page.
