Subject: sh: update INTC to clear IRQ sense valid flag
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8a5a778665efb3a5f16ebb6fbc13356907e45775;p=linux-beck.git

sh: update INTC to clear IRQ sense valid flag

Clear the valid flag is in the INTC code.
Without this fix bit 7 of the sense register
is mistakenly set.
