module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself. Scripted using git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file; do awk -i inplace ' /^#define EXPORT_SYMBOL_NS/ { gsub(/__stringify$ns$/, "ns"); print; next; } /^#define MODULE_IMPORT_NS/ { gsub(/__stringify$ns$/, "ns"); print; next; } /MODULE_IMPORT_NS/ { $0 = gensub(/MODULE_IMPORT_NS$([^)]*)$/, "MODULE_IMPORT_NS(\"\\1\")", "g"); } /EXPORT_SYMBOL_NS/ { if ($0 ~ /(EXPORT_SYMBOL_NS[^(]*)$([^,]+),/) { if ($0 !~ /(EXPORT_SYMBOL_NS[^(]*)\(([^,]+), ([^)]+)$/ && $0 !~ /(EXPORT_SYMBOL_NS[^(]*)/ && $0 !~ /^my/) { getline line; gsub(/[[:space:]]*\\$/, ""); gsub(/[[:space:]]/, "", line); $0 = $0 " " line; } $0 = gensub(/(EXPORT_SYMBOL_NS[^(]*)$([^,]+), ([^)]+)$/, "\\1(\\2, \"\\3\")", "g"); } } { print }' $file; done Requested-by: Masahiro Yamada Signed-off-by: Peter Zijlstra (Intel) Link: https://mail.google.com/mail/u/2/#inbox/FMfcgzQXKWgMmjdFwwdsfgxzKpVHWPlc Acked-by: Greg KH Signed-off-by: Linus Torvalds

gpio: Replace deprecated PCI functions

2024-11-07T13:10:34Z

pcim_iomap_regions() and pcim_iomap_table() have been deprecated by the PCI subsystem in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()"). Replace those functions with calls to pcim_iomap_region().

gpio: merrifield: Utilise temporary variable for struct device

2023-03-06T15:10:46Z

We have a temporary variable to keep pointer to struct device. Utilise it inside the ->probe() implementation. Signed-off-by: Andy Shevchenko

gpio: merrifield: make irq_chip immutable

2022-06-06T11:09:16Z

Since recently, the kernel is nagging about mutable irq_chips: "not an immutable chip, please consider fixing it!" Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new helper functions and call the appropriate gpiolib functions. Signed-off-by: Andy Shevchenko

gpio: merrifield: check the return value of devm_kstrdup()

2022-01-24T15:23:15Z

devm_kstrdup() returns pointer to allocated string on success, NULL on failure. So it is better to check the return value of it. Before, if devm_kstrdup() fails, pinctrl_dev_name will be NULL, then the retval below will be a negative error-code (inside gpiochip_add_pin_range(), pinctrl_find_and_add_gpio_range()->get_pinctrl_dev_from_devname() will finally check pinctrl_dev_name and return an error), so the failure of devm_kstrdup() can be only implicitly caught after a long call chain. While this patch is to explicitly catch the failure in time. Signed-off-by: Xiaoke Wang Signed-off-by: Andy Shevchenko

gpio: Bulk conversion to generic_handle_domain_irq()
