Subject: [PATCH 6/6] spi: altera: fix size mismatch on 64 bit processors
Date: Thu, 11 Jun 2020 11:25:11 +0800 [thread overview]
Message-ID: <1591845911-10197-7-git-send-email-yilun.xu@intel.com> (raw)
In-Reply-To: <1591845911-10197-1-git-send-email-yilun.xu@intel.com>
From: Matthew Gerlach <matthew.gerlach@linux.intel.com>
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.
