Clang warns:
drivers/mailbox/imx-mailbox.c:284:2: warning: variable 'val' is used
uninitialized whenever switch default is taken
[-Wsometimes-uninitialized]
default:
^~~~~~~
drivers/mailbox/imx-mailbox.c:288:7: note: uninitialized use occurs here
if (!val)
^~~
drivers/mailbox/imx-mailbox.c:263:9: note: initialize the variable 'val'
to silence this warning
u32 val, ctrl;
^
= 0
1 warning generated.
Prior to commit 91c8c1fbe498 ("mailbox: imx: add xSR/xCR register
array"), val was always initialized in imx_mu_isr() but now, it is not
initialized in the default case. Return IRQ_NONE like the statement
below does and add a message that there is an unhandled type for this
switch statement so that it can be updated.
Fixes: 91c8c1fbe498 ("mailbox: imx: add xSR/xCR register array")
