From a719a75a7761e4139dd099330d9fe3589d844f9b Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Wed, 30 Oct 2019 21:48:59 +0300 Subject: mtd: spi-nor: fix silent truncation in spi_nor_read() spi_nor_read() assigns the result of 'ssize_t spi_nor_read_data()' to the 'int ret' variable, while 'ssize_t' is a 64-bit type and *int* is a 32-bit type on the 64-bit machines. This silent truncation isn't really valid, so fix up the variable's type.
