wifi: mt7601u: delete dead code checking debugfs returns

2023-05-05T12:03:09Z

Smatch reports that: drivers/net/wireless/mediatek/mt7601u/debugfs.c:130 mt7601u_init_debugfs() warn: 'dir' is an error pointer or valid". Debugfs code is not supposed to need error checking so instead of changing this to if (IS_ERR()) the correct thing is to just delete the dead code.

wifi: mt7601u: fix clang -Wformat warning

2022-07-18T11:54:23Z

When building with Clang we encounter this warning: | drivers/net/wireless/mediatek/mt7601u/debugfs.c:92:6: error: format | specifies type 'unsigned char' but the argument has type 'int' | [-Werror,-Wformat] dev->ee->reg.start + dev->ee->reg.num - 1); The format specifier used is `%hhu` which describes a u8. Both `dev->ee->reg.start` and `.num` are u8 as well. However, the expression as a whole is promoted to an int as you cannot get smaller-than-int from addition. Therefore, to fix the warning, use the promoted-to-type's format specifier -- in this case `%d`. example: ``` uint8_t a = 4, b = 7; int size = sizeof(a + b - 1); printf("%d\n", size); // output: 4 ``` See more: (https://wiki.sei.cmu.edu/confluence/display/c/INT02-C.+Understand+integer+conversion+rules) "Integer types smaller than int are promoted when an operation is performed on them. If all values of the original type can be represented as an int, the value of the smaller type is converted to an int; otherwise, it is converted to an unsigned int."

mt7601u: use DEFINE_DEBUGFS_ATTRIBUTE to define debugfs fops

2019-10-31T08:10:35Z

It is more clear to use DEFINE_DEBUGFS_ATTRIBUTE to define debugfs file operation rather than DEFINE_SIMPLE_ATTRIBUTE. Signed-off-by: zhong jiang Acked-by: Jakub Kicinski Signed-off-by: Kalle Valo

add mt7601u driver

2015-05-28T08:33:20Z

Add support for the simplest of MediaTek Wi-Fi devices - MT7601U. It is a single stream bgn chip with no bells or whistles. This driver is partially based on Felix's mt76 but IMHO it doesn't make sense to merge the two right now because MT7601U is a design somewhere between old Ralink devices and new Mediatek chips. There wouldn't be all that much code sharing with the devices mt76 supports. Situation may obviously change when someone decides to extend m76 with support for the more recent USB dongles. The driver supports only station mode. I'm hoping to add AP support when time allows. This driver sat on GitHub for quite a while and got some testing there: http://github.com/kuba-moo/mt7601u Signed-off-by: Jakub Kicinski Signed-off-by: Kalle Valo
