Subject: [PATCH] habanalabs: fix kernel pointer type
Date: Mon, 26 Oct 2020 17:08:06 +0100 [thread overview]
Message-ID: <20201026160825.3706944-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
All throughout the driver, normal kernel pointers are
stored as 'u64' struct members, which is kind of silly
and requires casting through a uintptr_t to void* every
time they are used.
There is one line that missed the intermediate uintptr_t
case, which leads to a compiler warning:
drivers/misc/habanalabs/common/command_buffer.c: In function 'hl_cb_mmap':
drivers/misc/habanalabs/common/command_buffer.c:512:44: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
512 | rc = hdev->asic_funcs->cb_mmap(hdev, vma, (void *) cb->kernel_address,
Rather than adding one more cast, just fix the type and
remove all the other casts.
Fixes: 0db575350cb1 ("habanalabs: make use of dma_mmap_coherent")
