From 8fa76350587b6deb8a95d83f9cb23ce7599587b5 Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Fri, 28 Apr 2023 16:04:59 +0530 Subject: [PATCH] drm/amd/amdgpu: Fix style problems in amdgpu_debugfs.c MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Fix the following issues reported by checkpatch: WARNING: please, no space before tabs WARNING: Prefer 'unsigned int' to bare use of 'unsigned' WARNING: sizeof *rd should be sizeof(*rd) WARNING: Missing a blank line after declarations WARNING: sizeof rd->id should be sizeof(rd->id) WARNING: static const char * array should probably be static const char * const WARNING: Symbolic permissions 'S_IRUGO' are not preferred. Consider using octal permissions '0444'. WARNING: Prefer seq_puts to seq_printf ERROR: space prohibited after that open parenthesis '(' Cc: Christian König Cc: Alex Deucher Signed-off-by: Srinivasan Shanmugam Reviewed-by: Christian König Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c | 28 +++++++++++++++------------- 1 file changed, 15 insertions(+), 13 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c index cc64ae5..df94cd2 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c @@ -56,14 +56,14 @@ * * Bit 62: Indicates a GRBM bank switch is needed * Bit 61: Indicates a SRBM bank switch is needed (implies bit 62 is - * zero) + * zero) * Bits 24..33: The SE or ME selector if needed * Bits 34..43: The SH (or SA) or PIPE selector if needed * Bits 44..53: The INSTANCE (or CU/WGP) or QUEUE selector if needed * * Bit 23: Indicates that the PM power gating lock should be held - * This is necessary to read registers that might be - * unreliable during a power gating transistion. + * This is necessary to read registers that might be + * unreliable during a power gating transistion. * * The lower bits are the BYTE offset of the register to read.
