From aea8baa10ac5e9acddf80e48593fe85c22d19286 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 17 May 2017 16:46:55 +0200 Subject: [PATCH] rt2x00: convert rt2x00_rf_read return type This is a semi-automated conversion to change rt2x00_rf_read() to return the register contents instead of passing them by value, resulting in much better object code. The majority of the patch was done using: sed -i 's:\(\(.*, .*\), &\(.*\));:\2 = \1);:' \ drivers/net/wireless/ralink/rt2x00/rt* Signed-off-by: Arnd Bergmann Signed-off-by: Kalle Valo --- drivers/net/wireless/ralink/rt2x00/rt2400pci.c | 2 +- drivers/net/wireless/ralink/rt2x00/rt2500pci.c | 4 ++-- drivers/net/wireless/ralink/rt2x00/rt2500usb.c | 4 ++-- drivers/net/wireless/ralink/rt2x00/rt2800lib.c | 2 +- drivers/net/wireless/ralink/rt2x00/rt2x00.h | 11 ++--------- drivers/net/wireless/ralink/rt2x00/rt61pci.c | 10 +++++----- drivers/net/wireless/ralink/rt2x00/rt73usb.c | 10 +++++----- 7 files changed, 18 insertions(+), 25 deletions(-) diff --git a/drivers/net/wireless/ralink/rt2x00/rt2400pci.c b/drivers/net/wireless/ralink/rt2x00/rt2400pci.c index 3ba9a1674e1d..d41832292db2 100644 --- a/drivers/net/wireless/ralink/rt2x00/rt2400pci.c +++ b/drivers/net/wireless/ralink/rt2x00/rt2400pci.c @@ -199,7 +199,7 @@ static const struct rt2x00debug rt2400pci_rt2x00debug = { .word_count = BBP_SIZE / sizeof(u8), }, .rf = { - .read = _rt2x00_rf_read, + .read = rt2x00_rf_read, .write = rt2400pci_rf_write, .word_base = RF_BASE, .word_size = sizeof(u32), diff --git a/drivers/net/wireless/ralink/rt2x00/rt2500pci.c b/drivers/net/wireless/ralink/rt2x00/rt2500pci.c index d9b061b73e83..232feba0773f 100644 --- a/drivers/net/wireless/ralink/rt2x00/rt2500pci.c +++ b/drivers/net/wireless/ralink/rt2x00/rt2500pci.c @@ -199,7 +199,7 @@ static const struct rt2x00debug rt2500pci_rt2x00debug = { .word_count = BBP_SIZE / sizeof(u8), }, .rf = { - .read = _rt2x00_rf_read, + .read = rt2x00_rf_read, .write = rt2500pci_rf_write, .word_base = RF_BASE, .word_size = sizeof(u32), @@ -556,7 +556,7 @@ static void rt2500pci_config_txpower(struct rt2x00_dev *rt2x00dev, { u32 rf3;
