Subject: gpio: davinci: Use signed type for 'irq' variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=58c0f5aa124534af16d7faaf1abdfa0d9fec8290;p=linux-beck.git

gpio: davinci: Use signed type for 'irq' variable

Variable 'irq' is declared as unsigned and then used to store
negative return values from irq_alloc_descs() such as -EINVAL.
This patch fix this by declaring the variable as a signed.
