From d9dd0fb0e197ae766f0f5e06d23f5f5e1888c511 Mon Sep 17 00:00:00 2001 From: Matthew Gerlach Date: Fri, 19 Jun 2020 09:43:41 +0800 Subject: [PATCH] spi: altera: fix size mismatch on 64 bit processors The spi-altera driver was originally written with a 32 bit processor, where sizeof(unsigned long) is 4. On a 64 bit processor sizeof(unsigned long) is 8. Change the structure member to u32 to match the actual size of the control register.
