Subject: [PATCH v2 1/7] usb: gadget: pch_udc: Replace cpu_to_le32() by lower_32_bits()
Date: Tue, 23 Mar 2021 17:36:20 +0200 [thread overview]
Message-ID: <20210323153626.54908-1-andriy.shevchenko@linux.intel.com> (raw)
Either way ~0 will be in the correct byte order, hence
replace cpu_to_le32() by lower_32_bits(). Moreover,
it makes sparse happy, otherwise it complains:
.../pch_udc.c:1813:27: warning: incorrect type in assignment (different base types)
.../pch_udc.c:1813:27: expected unsigned int [usertype] dataptr
.../pch_udc.c:1813:27: got restricted __le32 [usertype]
Fixes: f646cf94520e ("USB device driver of Topcliff PCH")
