[PATCH v2 6/6] spi: altera: fix size mismatch on 64 bit processors

From: Xu Yilun
Date: Thu Jun 18 2020 - 11:29:22 EST


From: Matthew Gerlach <matthew.gerlach@xxxxxxxxxxxxxxx>

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.
