spi: sirf: avoid uninitialized-use warning
24778be20 "spi: convert drivers to use bits_per_word_mask"
removed the "default" statement in the spi_sirfsoc_setup_transfer
switch, causing a new warning:
drivers/spi/spi-sirf.c: In function 'spi_sirfsoc_setup_transfer':
arch/arm/include/asm/io.h:90:2: warning: 'rxfifo_ctrl' may be used uninitialized in this function [-Wmaybe-uninitialized]
asm volatile("str %1, %0"
^
drivers/spi/spi-sirf.c:364:19: note: 'rxfifo_ctrl' was declared here
u32 txfifo_ctrl, rxfifo_ctrl;
^
The compiler has correctly identified that this case may happen,
but since we know that things are horribly broken if bits_per_word
is ever something other than the values we tested, calling BUG()
is an appropriate action and tells the compiler that execution
will not continue afterwards.
