2019-07-30staging: Remove dev_err() usage after platform_get_irq()Stephen Boyd
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

We can safely get rid of all mtd_erase_callback() calls and all erase_info->state assignments.

2016-02-07staging: goldfish: use div64_s64 instead of do_divArnd Bergmann
The goldfish nand driver divides a signed 64-bit number (loff_t) in multiple places using the do_div() function. This has always been unreliable but now produces a compiler warning (since 4.5-rc1): goldfish/goldfish_nand.c: In function 'goldfish_nand_erase': goldfish/goldfish_nand.c:107:91: error: comparison of distinct pointer types lacks a cast [-Werror] goldfish/goldfish_nand.c: In function 'goldfish_nand_read_oob': goldfish/goldfish_nand.c:145:91: error: comparison of distinct pointer types lacks a cast [-Werror] This changes the code to the equivalent div_s64{,_rem} that works correctly for negative numbers (which we should never get here). The warning has shown up on ARM allmodconfig builds after the goldfish bus driver has become visible on ARM.

2015-05-31staging: goldfish: Fix pointer cast for 32 bitsPeter Senna Tschudin
As the first argument of gf_write64() was of type unsigned long, and as some calls to gf_write64() were casting the first argument from void * to u64 the compiler and/or sparse were printing warnings for casts of wrong sizes when compiling for i386. This patch changes the type of the first argument of gf_write64() to const void *, and update calls to the function. This change fixed the warnings and allowed to remove casts from 3 calls to gf_write64(). In addition gf_write64() was renamed to gf_write_ptr() as the name was misleading because it only writes 32 bits on 32 bit systems. gf_write_dma_addr() was added to handle dma_addr_t values which is used at drivers/staging/goldfish/goldfish_audio.c.

2015-03-16Staging: goldfish: use !x instead of x == NULLSomya Anand
Functions like devm_kzalloc, kmalloc_array, devm_ioremap, usb_alloc_urb, alloc_netdev return NULL as a return value on failure. Generally, When NULL represents failure, !x is commonly used. This patch cleans up the tests on the results of these functions, thereby using !x instead of x == NULL or NULL == x. This is done via following coccinelle script: @prob_7@ identifier x; statement S; @@ ( x = devm_kzalloc(...); | x = usb_alloc_urb(...); | x = kmalloc_array(...); | x = devm_ioremap(...); | x = alloc_netdev(...); ) ... - if(NULL == x) + if(!x) S Further we have used isomorphism characteristics of coccinelle to indicate x == NULL and NULL == x are equivalent. This is done via following iso script.
