Subject: usb: musb: dsps: fix build on i386 when COMPILE_TEST is set
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d30323f810e4da94eb75cf4bfe5165b9518c64df;p=openwrt%2Fstaging%2Fblogic.git

usb: musb: dsps: fix build on i386 when COMPILE_TEST is set

Commit 3e457371f436 ("usb: musb: Fix fifo reads for dm816x with musb_dsps")
fixed a USB error on dm816x, but introduced a new build error on i386
when COMPILE_TEST is set:

drivers/usb/musb/musb_dsps.c: In function ‘dsps_read_fifo32’:
drivers/usb/musb/musb_dsps.c:624:3: error: implicit declaration of function
‘readsl’ [-Werror=implicit-function-declaration]
readsl(fifo, dst, len >> 2);

Let's fix this by using ioread32_rep() instead of readsl() as that's
more portable.
