spi: bcm2835aux: Restore err assignment in bcm2835aux_spi_probe
[ Upstream commit d853b3406903a7dc5b14eb5bada3e8cd677f66a2 ]
Clang warns:
drivers/spi/spi-bcm2835aux.c:532:50: warning: variable 'err' is
uninitialized when used here [-Wuninitialized]
dev_err(&pdev->dev, "could not get clk: %d\n", err);
^~~
./include/linux/dev_printk.h:112:32: note: expanded from macro 'dev_err'
_dev_err(dev, dev_fmt(fmt), ##__VA_ARGS__)
^~~~~~~~~~~
drivers/spi/spi-bcm2835aux.c:495:9: note: initialize the variable 'err'
to silence this warning
int err;
^
= 0
1 warning generated.
Restore the assignment so that the error value can be used in the
dev_err statement and there is no uninitialized memory being leaked.
