spi: spi-bitbang: Fix conversion of spi_bitbang_transfer_one()
Since commit 2025172e3 (spi/bitbang: Use core message pump), the following
kernel crash is seen:
Unable to handle kernel NULL pointer dereference at virtual address 0000000d
pgd = 80004000
[0000000d] *pgd=00000000
Internal error: Oops: 5 [#1] SMP ARM
Modules linked in:
CPU: 1 PID: 48 Comm: spi32766 Not tainted 3.11.0-rc1+ #4
task: bfa3e580 ti: bfb90000 task.ti: bfb90000
PC is at spi_bitbang_transfer_one+0x50/0x248
LR is at spi_bitbang_transfer_one+0x20/0x248
...
,and also the following build warning:
drivers/spi/spi-bitbang.c: In function 'spi_bitbang_start':
drivers/spi/spi-bitbang.c:436:31: warning: assignment from incompatible pointer type [enabled by default]
In order to fix it, we need to change the first parameter of
spi_bitbang_transfer_one() to 'struct spi_master *master'.
Tested on a mx6qsabrelite by succesfully probing a SPI NOR flash.
