Subject: [PATCH 1/3] spi/spi-atmel: Fix format specifier warnings
Date: Tue, 30 Jul 2013 17:35:35 +0000 [thread overview]
Message-ID: <1375205737-3468-1-git-send-email-emilgoode@gmail.com> (raw)
This patch fixes the following sparse warnings.
dma_addr_t can be either u32 or u64 so we should cast to the
largest type and use the format specifier %llx.
drivers/spi/spi-atmel.c: In function ‘atmel_spi_next_xfer_dma_submit’:
drivers/spi/spi-atmel.c:631:2: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 7 has type ‘dma_addr_t’ [-Wformat]
drivers/spi/spi-atmel.c:631:2: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 9 has type ‘dma_addr_t’ [-Wformat]
drivers/spi/spi-atmel.c: In function ‘atmel_spi_pdc_next_xfer’:
drivers/spi/spi-atmel.c:734:3: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 7 has type ‘dma_addr_t’ [-Wformat]
drivers/spi/spi-atmel.c:734:3: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 9 has type ‘dma_addr_t’ [-Wformat]
drivers/spi/spi-atmel.c:773:3: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 7 has type ‘dma_addr_t’ [-Wformat]
drivers/spi/spi-atmel.c:773:3: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 9 has type ‘dma_addr_t’ [-Wformat]
